Based on the information provided, here's a breakdown of the acceptance criteria and the study that proves the device meets them:

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

The document doesn't present a single, explicit table of "acceptance criteria" with a corresponding "reported device performance" against those criteria in a pass/fail format for a clinical study. Instead, it details various bench tests and their outcomes, comparing the myPatch®s to its predicate device, myPatch®. The acceptance is implied by the "Substantially Equivalent" conclusion for each test.

Here's an attempt to synthesize the electrical performance aspects into such a table, based on the "Bench Testing" section:

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 describes bench testing, comparing the myPatch®s device directly against its predicate, myPatch®, and against established electrical standards. This is not a clinical study with human subjects that would typically involve a "test set" sample size in the usual sense for evaluating performance on patient data.

• Test Set Sample Size: Not applicable in the context of a clinical test set. The tests involve the physical devices (myPatch® and myPatch®s) and signal generators.
• Data Provenance: Not applicable as it's bench testing, not human data. The tests confirm the device's adherence to technical specifications.

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. Ground truth for bench testing is established by engineering specifications and standard requirements (e.g., IEC 60601-2-47, ANSI/AAMI EC12). The "ground truth" is the expected electrical output or performance according to these standards, not expert medical opinion on a diagnosis.

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

Not applicable. Adjudication methods are typically for resolving discrepancies in expert interpretations of clinical data, which is not what these bench tests entail.

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. This document does not mention any MRMC study. The device is a data acquisition device (ECG recorder), not an AI-powered diagnostic tool. The performance data focuses on its recording capabilities and electrical characteristics.

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

No, this is not an algorithm-only device. It's a medical device that records ECG data. The "software" mentioned refers to embedded firmware for data collection and processing, not a standalone diagnostic algorithm.

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

The ground truth used for these performance tests is based on engineering specifications and recognized international standards for medical electrical equipment (e.g., IEC 60601-2-47 for ambulatory ECG systems, IEC 60601-1-2 for EMC, ANSI/AAMI EC12 for electrodes). For biocompatibility, it refers to ISO 10993. The "ground truth" is the specified electrical performance, safety, and compatibility requirements.

8. The sample size for the training set

Not applicable. This device does not use machine learning in a way that would require a "training set" of data for an algorithm. The software is for device control and data storage, not for learning or diagnostic predictions.

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

Not applicable, as there is no training set for a machine learning algorithm.

The myPatch is indicated for use on patients who may be asymptomatic or who may suffer from transient symptoms such as palpitations, shortness of breath, dizziness, light headedness, presyncope, syncope, fatigue, chest pain and/or anxiety.

The myPatch ambulatory electrocardiograph(ECG) recorder is a small, lightweight monitor that records ECG continuously. The unit records 2 channel of ECG data up to 3 days. The device is composed of a large ECG electrode and ECG recorder. The ECG recorder clips onto the electrode and records until the recorder is removed from the electrode. At the end of the recorder can be plugged into a PC via the USB connection. The ECG recording can be transferred in an available file that can be processed through recording processing software provided by recording processing software manufacturers and analyzed by qualified healthcare providers.

The myPatch records ECG in accordance to the standard IEC 60601-2-47:2012 for ambulatory ECG recorders.

During the recording the patient wears the myPatch connected to an electrode on the sternym. The myPatch consists of a plastic casing containing a battery and electronics consisting of a microprocessor, measuring circult, memory, data storage, light-emitting dlode (transilluminates the plastic casing), and contact to the electrode. In addition to that, myPatch contains firmware to control the collection of the ECG-data and software to transfer to processing software.

The battery is a rechargeable lithium polymer battery with a built-in protection circuit. The charging of the myPatch is by use of a USB cable, which can only be connected to myPatch when it is not connected to the electrode. At the bottom of myPatch is an electrical and click-on connection for the electrode. myPatch must be connected to the electrode to turn on and to acquire data. myPatch has a serial number to secure the traceability of the equipment and the data during and after the investigation. myPatch is reusable.

The electrode ( accessory to myPatch, ) is the passive part. The electrode consists of one layer of onesided adhesive tape that runs the full length of the electrode. This adhesive tape allows the electrode to be placed on the sternum. The electrode gel is placed on the underneath side of the adhesive tape. Through this electrode gel, the ECG of the patient is measured. The top side of the electrode has an electrical and click-on connection to myPatch. The conductor paths are printed on the adhesive tape. These conductor paths make the connection between the electrode gel on the underside and the connection to myPatch on the top side of the electrode.

Release liners are placed on the underside and on the top side of the electrode. These release liners cover the adhesive tape and the electrode gel and are torn off when placing the myPatch on the sternum. The electrode has to be connected to myPatch to have any practical use. The electrode is a single- use device and is disposed of after one single use.
