A Modified Lewis ECG Lead System for Wearable Atrial Fibrillation Monitoring

Abstract

This study introduces a modified Lewis ECG lead configuration for wearable atrial fibrillation monitoring. The novel ECG lead configuration uses three leads from original Lewis lead system that are attached to the body places with less muscles. The proposed ECG lead configuration was compared with the original Lewis lead system in terms of atrial and ventricular activity amplitude in each lead. The results show that the proposed lead for atrial activity enhancement produces higher atrial activity amplitude comparing to the corresponding Lewis leads. Furthermore, modified Lewis ECG lead system provides addition lead with strongly enhanced ventricular activity. Such lead could be important for applications when lead with negligible atrial activity is essential.
