Hexoskin Medical System - ECG Performance Testing

HMS ECG Clinical Validation Study - Protocol External Site

The goal of this observational study is to validate the efficacy of the Hexoskin Medical System (HMS) for its intended use (i.e., manual assessment of cardiac rhythm disturbances) in non-critical adult participants who are suspected of having an arrhythmia or have evidence of arrhythmia requiring monitoring via 24-hour Holter monitor.

Study Overview

• Status: Completed
• Conditions: Cardiac Rhythm Disturbance
• Intervention / Treatment: Device: Hexoskin Medical System

Detailed Description

The main questions it aims to answer are:

1. Whether the HMS ECG recordings can be used to accurately detect cardiac beats when compared with the Holter monitor
2. Whether there are good agreements between the HMS and Holter monitor in ECG characteristics
3. Whether the HMS ECG recordings can be used to accurately classify cardiac rhythm/rhythm disturbance when compared with the Holter monitor
4. What is the accuracy of using HMS ECG recordings to detect cardiac beats
5. What is the accuracy of using HMS ECG recordings to identify cardiac rhythm/rhythm disturbance

Participants will wear the HMS and the Holter monitor at the same time to record ECG signals. Researchers will evaluate the ECG recordings acquired from both devices and assess the above questions.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Heart rate agreement	The agreement between HR calculated from the recordings acquired by the subject device and the reference Holter monitor.	2 days

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cardiac beat detection accuracy	The sensitivity and PPV of using the subject device recordings to detect cardiac beats.	2 days
Rhythm identification accuracy	The sensitivity and PPV of using the subject recordings to identify cardiac rhythm/rhythm disturbances.	2 days
ECG recording stability	The stability of the subject device for recording ECG through 24 hours of ambulatory ECG monitoring.	2 days
