Abstract

Bipolar ECG leads captured from sensors placed in a comfortable wearable-band on the left upper-arm, can provide ECG signals of sufficient quality after signal-enhancement processing, for reliable heart rhythm analysis in long-term ECG-monitoring and enabling clinical arrhythmias assessment. This study presents an inhouse built cable-free, wearable sensor system (WAMECG1) for a bipolar arm-ECG lead capture and wireless data transmission over a Wi-Fi link. The system’s functional blocks were integrated into a comfortable, ergonomically designed arm-band ECG wearable device.
A retrospective pilot analysis on the WASTCArD arm-ECG mapping database from our previous work, was carried out to find the optimal axis rotation of the bipolar arm-Lead electrodes pair, with respect to the body frontal plane and the arm axilla point; this was found to be at -60o axis rotation. Then, signal quality of the recorded far-field bipolar arm-ECG was validated in a pilot trial with 10 volunteer subjects at rest, using the prototype device. The overall R-peak detection accuracy was 99.67%. Without using any signal enhancement algorithm, the average signal-to-noise-ratio (SNR) values was 16.73. Therefore, the performance assessment results assured the performance of the wearable arm-band prototype device.
