The intended use of electrocardiograph is to acquire ECG signals from adult and pediatric patients through body surface ECG electrodes. The electrocardiograph is only intended to be used in hospitals or 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 ECG with measurements and interpretive statements is offered to clinician on an advisory basis only
The Smart ECG (SE) Series Electrocardiograph is designed to acquire, analyze, display, and record ECG signals from patient body surface by ECG electrodes. After been amplified, filtered and analyzed, The ECG signals waveforms and analysis results are displayed in the LCD and recorded in the paper through thermal printer or USB printer. ECG data, result and information of patient may be stored in the memory file. The file can be transmitted to PC through UART or Ethernet. Also the device can configure with the auto analysis software as optional which help to carry out auto measurement and auto interpretation. These devices consist of two basic components: the signal acquisition module and central processing unit. Models provide rechargeable battery. The SE Series Electrocardiograph can be divided into two type devices, SE-3, SE-300 series and SE-12, SE-1200 series. SE-3, SE-300 series are three channels Electrocardiograph, Including SE-300A, SE-300B, SE-3 (configuration with A and configuration with B ) , it can print out three channel electrocardiograph wave simultaneously by an 80mm wide thermal line printer. The difference between SE-3 and SE-300 is the device sheIl. SE-12, SE-1200 series are twelve or six channel Electrocardiograph, including SE-12, SE-12Express, SE-6, SE-1200, SE-1200Express, SE-600, it can print out twelve or six channel electrocardiograph wave simultaneously by a 216mm wide thermal line printer. the difference between SE-12 and SE-1200 is the device shell. The SE series Electrocardiograph is not intended to use in the emergency monitoring room.
Here's an analysis of the provided text regarding the acceptance criteria and study for the Edan Instruments Electrocardiograph:
The provided 510(k) summary for the Edan Instruments, Inc. Electrocardiograph (SE series) does not contain explicit details about specific quantitative acceptance criteria or a detailed clinical study proving device performance against such criteria. It largely focuses on substantial equivalence based on technological characteristics and general quality assurance measures.
The document indicates that the device's auto-analysis software and auto-interpretation features are optional and offered on an advisory basis only. This limits the need for a rigorous clinical performance study for these features as they are not presented as definitive diagnostic tools. The core approval focuses on the device's ability to acquire, analyze (measurements), display, and record ECG signals.
Without specific performance data, it's impossible to create the requested table of acceptance criteria and reported performance or answer several of the detailed questions about study design. However, I can extract what is provided and explain the limitations.
1. Table of Acceptance Criteria and Reported Device Performance
As mentioned, the document does not specify quantitative acceptance criteria for performance metrics like sensitivity, specificity, accuracy for interpretations, or specific measurement tolerances. Therefore, a table for these cannot be created from the given text.
The document states:
- "Verification and validation testing was done on the SE Electrocardiograph."
- "This premarket notification submission demonstrates that the SE Electrocardiograph is substantially equivalent to the cleared MAC 5000 because this device has the same basic intended use and the differences in technological characteristics do not raise new questions of safety or effectiveness."
This suggests the device met general safety and performance standards equivalent to its predicate, but no specific performance metrics are given.
2. Sample Size Used for the Test Set and Data Provenance
The document does not provide any information about the sample size of a test set, nor the data provenance (e.g., country of origin, retrospective or prospective) for any performance evaluation. This type of information would typically be found in a detailed clinical study report, which is not present here.
3. Number of Experts Used to Establish Ground Truth and Their Qualifications
The document does not specify a number of experts, their qualifications, or how ground truth was established for any performance test set. Given the "advisory basis only" statement for interpretations, a less stringent ground truth establishment might have been deemed acceptable, or the focus was primarily on signal acquisition accuracy, for which a different type of "ground truth" (e.g., comparison to a reference ECG machine) would be used.
4. Adjudication Method for the Test Set
The document does not mention any adjudication method for a test set.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
The document does not indicate that a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was conducted, nor does it provide any effect size for human readers improving with or without AI assistance. The optional "auto analysis software" and "auto interpretation" are presented as advisory, not as a tool designed to augment human reader performance in a clinical trial setting detailed here.
6. Standalone (i.e., algorithm only without human-in-the-loop performance) Study
The document does not explicitly describe a standalone performance study of the interpretation algorithm. While it mentions "auto analysis software as optional which help to carry out auto measurement and auto interpretation," no performance metrics for this standalone algorithm are provided. The "advisory basis only" statement suggests its performance might not have undergone a standalone clinical validation for diagnostic accuracy.
7. Type of Ground Truth Used
The document does not specify the type of ground truth used for any testing. Given the primary function is ECG signal acquisition and measurement, the "ground truth" might have been based on established ECG measurement standards and comparison to a predicate device's measurement accuracy, rather than clinical outcomes or pathology for interpretive accuracy.
8. Sample Size for the Training Set
The document does not provide any information about the sample size used for the training set of the auto-analysis software.
9. How the Ground Truth for the Training Set Was Established
The document does not provide any information about how the ground truth for the training set of the auto-analysis software was established.
Summary of Device and Approval Context:
The Edan Instruments Electrocardiograph received 510(k) clearance based on substantial equivalence to the MAC 5000 ECG Analysis System. The approval focuses on the device's ability to acquire, analyze (measurements), display, and record ECG signals. The auto-analysis and auto-interpretation features are presented as optional and advisory only, which likely reduced the regulatory burden for clinical performance studies specifically validating their diagnostic accuracy. The documentation emphasizes general quality assurance measures (software, hardware, safety, EMC testing) rather than detailed clinical performance studies of interpretive algorithms.
