Validation of wireless wearable electrocardiogram system for real-time ambulatory cardiac monitoring

Abstract

In our preliminary study, we proposed a wearable, power-proficient and multichannel ECG device, so-called wECG, aiming at real-time ambulatory cardiac monitoring. This paper targets the validation of wECG device using a reference system. The collected ECG signals from the developed device have been benchmarked with those from Polysomnography (PSG) system under exercising condition following a Bruce-based protocol. Compared to current ECG monitors, the proposed wearable ECG system can provide significant improvements in terms of device mobility, system inerrability, monitoring duration and signal quality. These improvements will enhance critically the home-based diagnosis and treatment of chronic cardiac disorders such as arrhythmia and atrial fibrillation.
