The indications for use for the PocketECG III monitor are as follows:

1. Patients who have a demonstrated need for cardiac monitoring. These may include but are not limited to patients who require monitoring for: a) non-life threatening arrhythmias such as supraventricular tachycardias (e.g. atrial fibrillation, atrial flutter, PACs. PSVT) and ventricular ectopy: b) evaluation of bradyarrhythmias and intermittent bundle branch block, including after cardiovascular surgery and myocardial infarction; and c) arrhythmias associated with co-morbid conditions such as hyperthyroidism or chronic lung disease;
2. Patients with symptoms that may be due to cardiac arrhythmias. These may include but are not limited to symptoms such as: a) dizziness or lightheadedness; b) syncope of unknown etiology in which arrhythmias are suspected or need to be excluded; and c) dyspnea(shortness of breath);
3. Patients with palpitations with or without known arrhythmias to obtain correlation of rhythm with symptoms;
4. Patients who require monitoring of effect of drugs to control ventricular rate in various atrial arrhythmias (e.g. atrial fibrillation);
5. Patients recovering from cardiac surgery who are indicated for outpatient arrhythmia monitoring;
6. Patients with diagnosed sleep disordered breathing including sleep apnea (obstructive, central) to evaluate possible nocturnal arrhythmias;
7. Patients requiring arrhythmia evaluation of etiology of stroke or transient cerebral ischemia, possibly secondary to atrial fibrillation or atrial flutter;
8. Data from the device may be used by another device to analyze, measure or report QT interval. The device is not intended to sound any alarms for QT interval changes.

PocketECG III - Medicalgorithmics Unified Arrhythmia Diagnostic System, type PECGT-IIIV is an ambulatory ECG monitor which analyzes electrographic signal, classifies all detected heart beats and recognizes rhythm abnormalities. All detection results, including annotations for every detected heart beat and the entire ECG signal are transmitted via cellular telephony network to a remote server accessible by a Monitoring Center for reviewing by trained medical staff.

The provided text does not contain detailed information about specific acceptance criteria and a study proving the device meets them in the format requested. While it outlines the device's indications for use, contraindications, and general technical specifications, it lacks the precise performance metrics, study design, and results typically found in such a document.

Here's an analysis based on the available information and what is missing:

1. Table of Acceptance Criteria and Reported Device Performance:

This information is not provided in the document. The text mentions that the device "meets the requirements of following performance standards" (IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, IEC 60601-2-47, and AAMI/ANSI EC57:2012), but it does not specify the numerical acceptance criteria derived from these standards for arrhythmia detection and the actual reported performance of the PocketECG III against those criteria.

2. Sample size used for the test set and data provenance:

This information is not provided in the document.

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

This information is not provided in the document. The text mentions "reviewing by trained medical staff" at a Monitoring Center, but it doesn't quantify or qualify these individuals regarding ground truth establishment for a test set.

4. Adjudication method for the test set:

This information is not provided in the document.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and its effect size:

This information is not provided in the document. The filing focuses on the device itself and its equivalence to a predicate, not on a human-in-the-loop study.

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

The document implies standalone performance testing against standards, as it states the device "analyzes electrographic signal, classifies all detected heart beats and recognizes rhythm abnormalities." It also mentions meeting "requirements of following performance standards," which would necessitate standalone testing of the algorithm's accuracy against a known truth. However, the specific details and results of such testing are not provided.

7. The type of ground truth used:

This information is not explicitly stated in the document. Given the nature of arrhythmia detection devices and the reference to standards like AAMI/ANSI EC57:2012, it is highly probable that the ground truth would involve expert cardiac rhythm annotations on ECG recordings. However, the document does not confirm this or describe the process.

8. The sample size for the training set:

This information is not provided in the document.

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

This information is not provided in the document.

Summary of what is present and relevant:

• Device: PocketECG III - Medicalgorithmics Unified Arrhythmia Diagnostic System, type PECGT-IIIV
• Purpose: Ambulatory ECG monitor that analyzes electrographic signals, classifies heartbeats, and recognizes rhythm abnormalities.
• Process: Detects, annotates, and transmits ECG signal and detection results via cellular network to a remote server for review by trained medical staff.
• Standards Mentioned: IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, IEC 60601-2-47, and AAMI / ANSI EC57:2012. The document states the device "meets the requirements" of these standards. This implies that some form of performance testing against criteria derived from these standards was conducted for substantial equivalence.

In conclusion, the provided text is a 510(k) summary for regulatory clearance, focusing on demonstrating substantial equivalence to a predicate device and adherence to general safety and performance standards. It does not delve into the detailed scientific study design, specific performance metrics, and results that would fully address all parts of your request regarding acceptance criteria and their proof.
