Device Description

The View 12 ECG Analysis Module provides means for performing diagnostic ECG analysis in conjunction with the monitoring functions of Datascope's Passport 2 Vital Signs Monitor (K993531). The View 12 ECG Analysis Module for the Passport 2 Vital Signs Monitor enables 12-Lead ECG Acquisition. Continuous 12-Lead ST Segment Analysis and Arrhythmia Analysis all with print capabilities. The View 12 ECG Analysis Module consists of a PCMCIA ECG processor card that interfaces with the Passport 2, a front-end electronics cable, and a detachable patient cable with integral leadwire set. The data acquired by this module is interpreted utilizing Mortara Instrument's algorithm (cleared by FDA under notification numbers: K920627, K920626A and K933143) for interpretive electrocardiographs. With the View 12 ECG Analysis Module installed and enabled, the Passport 2 makes interpretive statements on printouts. These statements are categorized into three (3) sections: an interpretive statement, a condition statement, and a rhythm statement.

AI/ML Overview

The provided 510(k) summary (K020532) for the Datascope Passport 2® Vital Signs Monitor with View 12™ ECG Analysis Module does not directly provide acceptance criteria or detailed results from a study specifically conducted for this 510(k) submission to prove the device meets acceptance criteria.

Instead, the submission relies on the concept of substantial equivalence to predicate devices. Here's what can be extracted and inferred regarding the study that proves the device meets acceptance criteria, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance:

The document does not contain a specific table outlining acceptance criteria and reported performance for the View 12 ECG Analysis Module itself.

However, the submission states:

"The diagnostic ECG algorithm used in Datascope's View 12 ECG Analysis Module is identical to that found in the Spacelabs' Integrated Multiparameter Module 90496, as well as in the Mortara Instrument ELI-100 (K920627), ELI-200 (K920626A) and ELI-300 (K933143.)"
"The functionality of the Passport 2 Vital Signs monitor with View 12 ECG Analysis Module is identical to that of the Spacelabs Ultraview 1050 monitor equipped with Integrated Multiparameter Module 90496."

Therefore, the "acceptance criteria" for the ECG analysis algorithm are implicitly the performance specifications already met and cleared for the predicate Mortara Instrument devices (K920627, K920626A, K933143) and the Spacelabs Module 90496. The reported device performance is, by definition of substantial equivalence in this context, assumed to be identical to these predicate devices. The submission asserts that the Datascope device's algorithm performs as well as the previously cleared Mortara algorithm because it is the Mortara algorithm.

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

The document does not explicitly state the sample size (number of patients/ECGs) for a test set for this specific 510(k) submission to validate the ECG algorithm.

Given the reliance on the predicate Mortara algorithm, the testing data would have been part of the original 510(k) submissions for Mortara Instrument ELI-100 (K920627), ELI-200 (K920626A) and ELI-300 (K933143). Without access to those original submissions, the sample size and data provenance remain unknown from this document. It is highly likely the data would have been retrospective, as is common for established ECG algorithm validation.

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

This information is not provided in the K020532 document, as the ECG algorithm itself was cleared in prior 510(k)s (Mortara Instrument devices). The original Mortara submissions would contain this detail. Typically, expert cardiologists or electrophysiologists with significant experience would be used for manual adjudication of ECGs to establish ground truth.

4. Adjudication Method for the Test Set:

This information is not provided in the K020532 document. It would have been part of the original Mortara submissions. Standard adjudication methods for ECGs often involve a consensus of multiple cardiologists (e.g., 2-out-of-3 agreement, or a tie-breaker by a senior expert).

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done:

No MRMC comparative effectiveness study is mentioned for the View 12 ECG Analysis Module in this 510(k) summary. The submission's argument is that the algorithm is the predicate algorithm, thus no new large-scale comparative study is required for algorithm performance.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done:

Yes, implicitly. The performance of the diagnostic ECG algorithm (Mortara's algorithm) was assessed in a standalone manner when it was originally cleared under K920627, K920626A, and K933143. This 510(k) leverages that prior clearance.

7. The Type of Ground Truth Used:

For ECG interpretation algorithms, the ground truth is almost exclusively expert consensus by qualified cardiologists or electrophysiologists. This would have been the case for the underlying Mortara algorithm.

8. The Sample Size for the Training Set:

This information is not provided in the K020532 document. The training data for the Mortara algorithm would have been developed prior to its initial 510(k) clearances.

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

This information is not provided in the K020532 document. For ECG algorithms, ground truth for training data would also typically be established through expert consensus, often with a similar process to, but distinct from, the ground truth establishment for the independent test set.

Summary of Device Acceptance Rationale (based on the provided text):

The Datascope Passport 2® Vital Signs Monitor with View 12™ ECG Analysis Module's acceptance is based on its substantial equivalence to legally marketed predicate devices. Specifically:

Functionality: The overall device functionality (Passport 2 with View 12) is stated to be identical to the Spacelabs Ultraview 1050 monitor with Integrated Multiparameter Module 90496.
ECG Algorithm: The diagnostic ECG algorithm itself is identical to one already cleared and used in several Mortara Instrument devices (K920627, K920626A, K933143) and the Spacelabs module. These predicate devices have already demonstrated compliance with performance standards and safety through their own clearance processes.
Safety and Performance Testing: The Datascope device underwent "extensive safety and performance testing" and complies with various industry and safety standards (e.g., ANSI/AAMI EC11, EC13, IEC 60601 series, ISO 10993-1, EN 1441). This testing would focus on the integration of the module, electrical safety, EMC, and ensuring that the overall device still meets general performance requirements, not necessarily re-validating the intrinsic accuracy of the ECG interpretation algorithm, which is assumed from its predicate status.

In conclusion, the "study that proves the device meets the acceptance criteria" for the ECG analysis algorithm refers to the studies conducted for the original Mortara Instrument devices (K920627, K920626A, K933143) because the Datascope device uses the identical, previously cleared algorithm. This 510(k) primarily establishes that the integration of this already cleared algorithm into a new monitor platform does not raise new questions of safety or effectiveness.

Intended Use

The SpaceLabs Medical 12-Lead Diagnostic ECG Analysis Option provides a means for performing diagnostic ECG analysis in conjunction with the monitoring functions of the SpaceLabs Medical Model 90492 ECG module. Diagnostic ECG analyzes detailed ECG waveforms in each cardiac cycle and the beat-to-beat variability in order to determine the cardiac rhythm. When used in conjunction with a SpaceLabs Medical Patient Care Management System (PCMS) monitor the SpaceLabs Medical Model 90492 ECG module provides a means for the continuous monitoring of electrocardiographic signals in order to detect abnormal cardiac rhythms, including life-threatening events.

Device Description

The SpaceLabs Medical 12-Lead Diagnostic ECG Analysis Option is a softwareonly option added to the 90492 module software, and is designed to acquire, analyze and display up to twelve ECG vectors in a standard diagnostic ECG analysis format and to work exclusively within the SpaceLabs Medical 90492 12lead ECG module. The diagnostic analysis algorithm is that used in the Mortara Instruments ELI 100 (K920627), ELI 200 (K920626A) and ELI 300 (K933143) and is provided by Mortara Instruments as object code. There is no additional hardware required for this option.

The SpaceLabs Medical Model 90492 ECG module is designed to acquire, process and display up to twelve ECG leads and one respiratory effort signal using standard ECG electrodes. The twelve ECG leads consist of the standard twelve ECG leads, I, II, III, aVR, aVL, aVF, V1 - V6. The 90492 ECG module is used to monitor patients in the operating room, recovery rooms, intensive care units, in the emergency room, in research settings, or other units where additional ECG leads are desired.

ECG data is displayed as an analog moving waveform or as various static waveforms. The analog ECG is passed through digital filters to eliminate unwanted signals. Standard ECG electrodes are used to interface the patient to the 90492 ECG module. Clinicians will position the electrodes in the customary locations. The electrodes are connected to shielded leadwires which are connected to a shielded cable. The cable is connected to the front of the 90492 module.

AI/ML Overview

Unfortunately, the provided text does not contain the detailed information needed to fully answer your request. The document is a 510(k) summary for a medical device and primarily focuses on describing the device, its intended use, and its equivalence to a predicate device.

Here's what I can extract and what's missing:

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

Acceptance Criteria: Not explicitly stated in terms of specific performance metrics (e.g., sensitivity, specificity, accuracy thresholds for ECG interpretation). The document generally states that "extensive safety and performance testing" was done and that the device "meets all of its functional requirements and performance specifications."
Reported Device Performance: Not provided. The summary confirms that the diagnostic ECG algorithm is identical to those found in the Mortara Instrument ELI300 (K933143), ELI 100 (K920627), and ELI 200 (K920626A). To find performance, one would need to consult the 510(k) summaries or supporting documentation for those predicate devices, as this document asserts identical performance due to using the same algorithm.

Missing Information for a comprehensive table: Specific metrics (e.g., detection rates for specific arrhythmias, accuracy of QRS duration measurement, etc.) and quantitative results against those metrics.

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

Sample Size: Not mentioned for any test set.
Data Provenance: Not mentioned.
Retrospective or Prospective: Not mentioned.

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 mentioned.
Qualifications of Experts: Not mentioned.

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

Not 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:

MRMC Study: Not mentioned. The device is described as a "Diagnostic ECG Analysis Option" which implies an algorithm that provides the analysis, but it doesn't describe a study comparing human readers with and without this algorithm's assistance.

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

The document implies this is a standalone algorithm's performance inherited from the predicate devices. It states, "The SpaceLabs Medical 12-Lead Diagnostic ECG Analysis Option is a software-only option... The diagnostic analysis algorithm is that used in the Mortara Instruments ELI 100 (K920627), ELI 200 (K920626A) and ELI 300 (K933143) and is provided by Mortara Instruments as object code." This suggests the algorithm's performance itself was assessed (or accepted based on predicate devices) without necessarily involving human-in-the-loop studies for this specific submission. However, the details of that standalone performance are not present here.

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

Not mentioned. For ECG analysis, ground truth often involves expert cardiologist consensus readings.

8. The sample size for the training set:

Not mentioned.

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

Not mentioned. Given that the algorithm is described as "identical to those found in the Mortara Instrument ELI300," the training and ground truth establishment would have occurred during the development and clearance of those earlier Mortara devices.

In summary: This 510(k) summary primarily focuses on regulatory equivalence to predicate devices, asserting that the device is "as safe and effective as the predicate device and raises no new issues" because it uses an identical, previously cleared algorithm. It does not provide the detailed performance study information typically requested for new algorithm submissions or when demonstrating specific performance against acceptance criteria. To obtain such details, one would need to review the K933143, K920627, or K920626A submissions for the Mortara Instrument devices.
