The intended use of SE-12 series electrocardiograph is to acquire ECG signals from adult and pediatric patients through body surface ECG electrodes. The electrocardiograph is only intended to healthcare facilities by doctors and trained healthcare professionals. The cardiogram recorded by the electrocardiograph can help users to analyze and diagnose heart disease. However, the interpreted ECG with measurements is offered to clinicians on an advisory basis only.

The SE-12/12 Express/1200/1200 Express Electrocardiograph gathers ECG signals of 12 leads simultaneously. It displays the operation menu, ECG parameters as well as electrocardiograms, and be powered by the mains supply or battery. And the system has advanced performance and high reliability due to high resolution thermal recorder, 32-bit processor and a large-capacity memorizer. Design of the system took much consideration on ergonomics so the size is suitable for clinic and hospital uses. There are four selectable modes in the system, including manual, auto, rhythm, R-R analysis or VCG, and VCG is configured with SE-12 Express & SE-1200 Express. SE-12 and SE-1200 share the same single color LCD screen of which the resolution is 320×240 dot; and LCD screen of SE-12 Express and SE-1200 Express is 800×600 multicolor LCD screen. Moreover, SE-12 Express is configured with stress ECG function, which will allow to diagnose concealed coronary heart disease and atypical angina pectoris, prescribe the workload for patients with myocardial infarction before leaving hospital, and assess the effect of the treatment.

The provided document is a 510(k) premarket notification for Electrocardiograph Models SE-12, SE-12 Express, SE-1200, and SE-1200 Express by Edan Instruments, Inc. It details the device comparison and performance data, but it does not describe specific acceptance criteria in terms of diagnostic performance metrics (e.g., sensitivity, specificity) for the ECG interpretation algorithm, nor does it present a study proving the device meets such criteria.

Instead, the document focuses on demonstrating substantial equivalence to predicate devices through:

• Comparison of intended use, safety specifications, environmental specifications, and performance specifications.
• Non-clinical testing, including biocompatibility, electrical safety/EMC, bench testing against IEC standards, and software verification/validation.

Here's an analysis of the requested information based on the provided text, highlighting where information is not available:

1. Table of acceptance criteria and the reported device performance

The document does not explicitly state quantitative diagnostic acceptance criteria (e.g., minimum sensitivity or specificity for detecting heart conditions) for its ECG interpretation capabilities. The closest information is comparisons of general performance specifications with predicate devices and compliance with safety and electrical standards.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Sample Size for Test Set: Not specified for any diagnostic performance evaluation. The document states "Clinical data: Not applicable," which implies no specific clinical test set for evaluating diagnostic accuracy was used or required for this 510(k) submission.
• Data Provenance: Not applicable, as no clinical test set data is described. The device is manufactured in China (Shenzhen, P.R. China).

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

• Not applicable. No clinical test set data or expert-established ground truth is described. The device's integrated interpretation uses specific algorithms (Glasgow, SEMIP) which are compared to those in predicate devices. The interpreted ECG with measurements and interpretive statements is "offered to clinicians on an advisory basis only," suggesting that the device's output is not intended as a definitive ground truth in itself.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Not applicable. No clinical test set and thus no adjudication method for ground truth establishment is described.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

• No MRMC comparative effectiveness study is mentioned. The submission states, "Clinical data: Not applicable."

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

• While the device includes an ECG interpretation algorithm (Glasgow/SEMIP), the document does not present a standalone performance study in terms of diagnostic accuracy (e.g., sensitivity, specificity, accuracy against a clinical gold standard). The focus is on the device's technical specifications and substantial equivalence to previously cleared devices that also include such algorithms, with the understanding that the interpretation is advisory. The "Bench Testing" (IEC 60601-2-25: 2011) primarily assesses the technical performance of the electrocardiograph (e.g., frequency response, noise, gain, etc.), not the diagnostic accuracy of its interpretive algorithm against clinical outcomes or expert diagnoses.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

• Not applicable for diagnostic performance. For the technical and safety performance, the "ground truth" is adherence to international and national standards (e.g., IEC 60601 series, ISO 10993-1, UL standards).

8. The sample size for the training set

• Not specified. The document describes the device as incorporating existing algorithms (Glasgow, SEMIP) found in predicate devices. Details about the training set for these algorithms (if they are considered "AI" in the modern sense) are not provided within this 510(k) summary.

9. How the ground truth for the training set was established

• Not specified. As noted above, details about the training of the Glasgow or SEMIP algorithms are not part of this submission.

The intended use of PADECG is to acquire resting ECG signals from adult and pediatric patients through body surface ECG electrodes. It is only intended to be used in hospitals or healthcare facilities by doctors and trained healthcare professionals. The cardiogram recorded by PADECG can help users to analyze and diagnose heart disease. However, the interpreted ECG with measurements and interpretive statements is offered to clinicians on an advisory basis only. It is mainly used in ECG inpatient department of hospitals or healthcare facilities.

PADECG is iPad-Based ECG work station. PADECG System primarily composed of DX12(iOS) Transmitter and PADECG Analysis Software, the product is designed to collect and analyzes 12-Lead resting ECG. The DX12(iOS) Transmitter contains lead wires and sends the ECG data to PADECG Analysis Software through Bluetooth. The PADECG Analysis Software will be uploaded to the App Store, so that customers can download it to their own iPad and install it. The PADECG Analysis Software which is installed in the iPad can display the ECG data. The PADECG Analysis Software can analysis the ECG data, and provide an advisory diagnostic result.

The provided text describes the 510(k) premarket notification for the Edan Instruments, Inc. PC ECG, model PADECG. The information focuses on demonstrating substantial equivalence to a predicate device (Edan Instruments, Inc., SE-1515, K152427) rather than providing detailed acceptance criteria and a study proving the device meets those criteria for its interpretive statements.

However, based on the information available and common regulatory practices for ECG devices with interpretive capabilities, we can infer some details regarding the "ECG interpretation feature validation by database testing" mentioned.

Here's an attempt to answer your questions based on the provided text, and where information is not explicitly stated, common practice for similar devices is used as a reasonable inference:

1. A table of acceptance criteria and the reported device performance

The document does not explicitly state a table of acceptance criteria for the interpretive algorithm's performance (e.g., sensitivity, specificity for specific diagnoses). Instead, it mentions that "ECG interpretation features were also validated by database testing." The "Comparison between PADECG and Predicate Device SE-1515" table (pages 4-5) details technical specifications of the device itself and explicitly states:

• Agreement with measurements: High correlation (e.g., R-squared > 0.95) and minimal bias in automated measurements of intervals (PR, QRS, QT), amplitudes (P, QRS, T), and axes compared to expert measurements.
• Clinical Significance: Demonstrating that the advice provided by the algorithm does not lead to significant misdiagnosis or harm when used as an advisory tool.

Given that the PADECG uses the "Algorithm of the Smart ECG Measurement and Interpretation Programs (SEMIP), version 1.8," which is the same algorithm as its predicate device (SE-1515), the primary evidence for meeting acceptance criteria for interpretation relies on the predicate device's prior validation and the demonstration that the PADECG implements this identical, validated algorithm correctly. The statement "ECG interpretation features were also validated by database testing" for the PADECG suggests that this algorithm's performance was confirmed on a test set, likely to ensure its faithful implementation on the new platform.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Sample Size: Not specified. The document only states "database testing."
• Data Provenance: Not specified (e.g., country of origin, retrospective/prospective). This is a common omission in 510(k) summaries, which often focus on the type of testing rather than granular details of the dataset.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

• Number of Experts: Not specified.
• Qualifications of Experts: Not specified. For ECG interpretation, ground truth is typically established by board-certified cardiologists or electrophysiologists, often with significant experience in ECG reading.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Adjudication Method: Not specified. For ECG interpretation, consensus or adjudication by multiple expert readers is standard practice to establish ground truth.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

• MRMC Comparative Effectiveness Study: No, the document does not mention an MRMC comparative effectiveness study where human readers' performance with and without AI assistance was evaluated. The device's interpretation is clearly stated as "advisory basis only," indicating it's not a standalone diagnostic device but a tool that assists a professional.
• Effect Size of Improvement: Not applicable, as no such study was reported.

6. If a standalone (i.e. algorithm only, without human-in-the-loop performance) was done

• Standalone Performance: Yes, implicitly. The "ECG interpretation features were also validated by database testing" refers to the performance of the algorithm itself against a pre-established ground truth. While the device is not standalone in general clinical use (it advises clinicians), the algorithm's performance in interpreting ECGs from the database is a standalone evaluation of its output against ground truth. The device is cleared as an "advisory" tool, meaning its standalone diagnostic accuracy is assessed but not necessarily expected to be perfect or replace human judgment.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

• Type of Ground Truth: Not explicitly stated but heavily implied to be expert consensus or reference standard ECG interpretations derived from cardiologists. For ECG interpretation, this is the gold standard for validating algorithms. Pathology or outcomes data are generally not the direct ground truth for ECG interpretation algorithms, though they might be used in broader clinical studies of the overall diagnostic pathway.

8. The sample size for the training set

• Training Set Sample Size: Not specified. The document focuses on the validation of the interpretation features via "database testing" for the specific device being cleared. Details of the training set used for the original development of the "SEMIP, version 1.8" algorithm are not provided in this 510(k) summary.

9. How the ground truth for the training set was established

• Training Set Ground Truth Establishment: Not specified in this document. For the original development of the SEMIP algorithm, it would likely have involved a large dataset of ECGs interpreted by multiple cardiologists, with discrepancies resolved through an adjudication process to establish the most accurate ground truth.

ECG is intended to disclose either normal condition or patterns of arrhythmia, myocardial ischemia, rate abnormalities, or features of prognostic value in patients:
l ) suspected of cardiac abnormalities, or
2) in populations of patients at an age or period in which a routine baseline evaluation of ECG characteristics are desired.
3) OT Analysis is useful in the assessment of long QT syndrome (LQTS). In some instances, LQTS can be corrected by pharmacologic therary. QT analysis is also used to measure QT dispersion, the difference between maximal and minimal QT values. QT dispersion is a measure of the inhomogeneity of ventricular repolarization. 4) The PC ECG 1200W System has been tested to measure Heart Rate Variability within 1 millisecond tolcrance. The clinical significance of Heart Rate Variability measures should be determined by a physician.
5) The PC ECG 1200W System has been tested to measure Latc Potential within 1 millisecond tolerance in the time domain, and I microvolt tolerance in voltage. The clinical significance of Heart Rate Variability measures should be determined by a physician.

Stress testing intended use:
Angina pectoris (chest pain) is a clinical syndrome resulting from myocardial ischemia, indicative of a reduced blood supply to the cardiac muscle. The electrocardiogram may establish the diagnosis of ischemic heart disease if characteristic changes are present. Stress testing is the most widely used method to decide whether this chest pain is related to myocardial ischemia, and thereby coronary artery disease. In stress testing, the contractile capability of the heart muscle is monitored via ECG during patient exercise. Patients are exercised by bicycle, treadmill, or other means while continuously monitoring the ECG. Exercise loads are determined by predefined protocols. The ECG signals are recorded for the resting, exercise and recovery portions of the exercise protocol. The changes in ECG waveforms are compared to the resting ECG records. Although not necessary, most of the commercial stress test systems control the bicycle or treadmill automatically according to the requirements of the chosen protocol.
ST segment monitoring is intended as an aid in the evaluation of myocardial ischemia in patients with known or suspected coronary artery disease. The ST segment algorithm has been tested for accuracy of the ST segment data, and a database has been used as a tool for performance testing. The significance of the ST segment changes must be determined by a physician.

The PC ECG 1200W System is designed to disclose either normal condition or patterns of arrhythmia, myocardial ischemia, rate abnormalities, or features of prognostic value. The System comprises:

• · PCECG 1200W data acquisition unit
• · PCECG 1200WR RF transceiver
• · USB communications cable
• · Software application
• · Software security lock (dongle) for access to stress testing functions (optional)

The NORAV PC ECG 1200W System is substantially equivalent to the predicate device, Norav's PC ECG 1200 K000404, with the primary difference being the addition of wireless data communication capabilities. The submission primarily focuses on the device's technical specifications and intended use, asserting its safety and reliability based on similarity to the predicate and adherence to recognized standards.

The provided document describes the device's intended functionality and accuracy in certain measurements, but it does not explicitly state specific pass/fail acceptance criteria in a quantitative manner for most functions. Instead, it makes claims of the device's capabilities and how it has been tested.

2. Sample Size Used for the Test Set and Data Provenance:

• Test Set Sample Size: The document mentions that for the ST segment algorithm, "a database has been used as a tool for performance testing." However, no specific sample size for this database or any other test set is provided.
• Data Provenance: Not specified. It does not mention the country of origin, nor whether the data was retrospective or prospective.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:

• This information is not provided in the document. The document states that "The significance of the ST segment changes must be determined by a physician," but it does not detail how ground truth was established for the performance testing database.

4. Adjudication Method for the Test Set:

• This information is not provided in the document.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

• A MRMC comparative effectiveness study was not mentioned or implied in the provided summary. The submission focuses on device equivalence and performance claims rather than comparing human reader performance with and without AI assistance.

6. Standalone (Algorithm Only) Performance:

• The claims regarding Heart Rate Variability ("within 1 millisecond tolerance") and Late Potential analysis ("within 1 millisecond tolerance in the time domain, and 1 microvolt tolerance in voltage") appear to relate to the standalone performance of the device's algorithms or measurement capabilities.
• Similarly, the statement that "The ST segment algorithm has been tested for accuracy of the ST segment data, and a database has been used as a tool for performance testing" indicates a standalone algorithmic test.
• However, specific metrics or a detailed study of standalone performance results (e.g., sensitivity, specificity, AUC) are not explicitly provided beyond the tolerance statements for HRV and Late Potential.

7. Type of Ground Truth Used:

• For Heart Rate Variability and Late Potential analysis, the "tolerance" statements imply the device's measurements were compared against a reference standard for accuracy, which would constitute the ground truth. However, the nature of this reference standard (e.g., a gold standard measurement, expert-derived ground truth) is not specified.
• For the ST segment algorithm, it states a "database has been used as a tool for performance testing." The ground truth for this database to assess "accuracy" of ST segment data is not explicitly stated (e.g., expert consensus, pathology, follow-up outcomes). The "significance of the ST segment changes must be determined by a physician" suggests clinical interpretation is ultimately required.

8. Sample Size for the Training Set:

• This information is not provided in the document. The document refers to "testing" with a database but does not distinguish between training and test sets.

9. How the Ground Truth for the Training Set Was Established:

• As no information about a training set is provided, the method for establishing its ground truth is also not mentioned.

Ask a specific question about this device

The CardioSoft PC ECG is intended for use in acquiring, processing, recording, archiving and displaying electrocardiographic information. It can provide serial comparison of ECG information to facilitate review of current and previous records and is intended for use by trained operators. The system offers no diagnostic opinion to the user, but may be used by a physician to render his or her own medical opinion.

The CardioSoft PC ECG is an electrocardiograph that detects signals associated with cardiac activity and produces an ECG graphical record. The device operates on a personal computer through a USB hardware module. The device can acquire, process, record, archive and display 3-, 6-, or 12-lead ECG and vector cardiograms. The device provides portable ECG with important advantages compared to traditional machines.

The presented document is a 510(k) summary for the CardioSoft PC ECG device, a substantially equivalent submission to the predicate device CARDIAX (K924544). The document does not describe specific acceptance criteria or a dedicated study to prove the device meets performance criteria through clinical data or comparative effectiveness. Instead, it relies on demonstrating substantial equivalence to a predicate device and compliance with recognized standards.

Here's a breakdown of the requested information based on the provided text:

1. A table of acceptance criteria and the reported device performance

The document explicitly states: "The FDA has not established performance standards for this device." Therefore, there are no specific FDA-mandated acceptance criteria or direct reported device performance metrics (e.g., sensitivity, specificity, accuracy) derived from a clinical study for this 510(k) submission.

The "performance" section instead focuses on demonstrating equivalence through non-clinical testing and adherence to quality assurance measures.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The document does not describe a clinical "test set" with a specific sample size. The performance assessment relies on non-clinical testing and comparison to a predicate device. Therefore, no information on data provenance (country of origin, retrospective/prospective) for a clinical test set is provided.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. As no clinical test set or ground truth establishment process for diagnostic performance is described, there's no mention of experts or their qualifications in this context.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. There is no clinical test set described in the submission, therefore no adjudication method is mentioned.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

No. The document makes no mention of a multi-reader multi-case (MRMC) comparative effectiveness study. The device, an electrocardiograph, "offers no diagnostic opinion to the user" and there is no AI component mentioned that would assist human readers in a diagnostic setting.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

The device is an "electrocardiograph that detects signals associated with cardiac activity and produces an ECG graphical record." It is not an algorithm providing diagnostic output without human interpretation. It generates a record "that may be utilized only by a qualified healthcare professional for review and interpretation when based upon patient history, medical examination, and other clinical findings." Therefore, a standalone algorithm-only performance study as typically understood for AI-driven diagnostic tools was not conducted or described. The "performance" refers to the device's ability to accurately acquire, process, record, archive, and display ECG information.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

Given the nature of the device (ECG acquisition and display) and the absence of a clinical diagnostic performance study, the concept of "ground truth" as typically applied to diagnostic algorithms (e.g., expert consensus for disease presence or absence, pathology results) is not relevant or mentioned in this submission. The "ground truth" for demonstrating performance would likely involve the accuracy of signal acquisition, processing, and display compared to known electrical signals or established ECG benchmarks.

8. The sample size for the training set

Not applicable. The CardioSoft PC ECG is described as an upgrade/modification of an existing device, preserving the "software processes of the predicate device." It's not a machine learning or AI-driven device that typically requires a 'training set' in the conventional sense for a 510(k). The focus is on hardware and interface improvements while maintaining functional equivalence.

9. How the ground truth for the training set was established

Not applicable, as there is no mention of a training set for a machine learning model.
