WIRELESS ECG AND HEART RATE MONITORING USING DUAL GROUND DRY ELECTRODES

Joan Gómez-Clapers, Ramon Casanella

Abstract

In this work, a novel wireless easy-to-use measuring system is presented to acquire the Lead I ECG signal and the heart rate. The system presents a novel application of the dual ground configuration to dry electrodes, to reduce their level of power line interference. With this, a good quality Lead I EGC signal can be obtained simply by placing the right and left hands on the dual electrodes. Heart rate is obtained with a novel algorithm based on the continuous wavelet transform (CWT), especially designed to avoid the electromyographic noise that can be present when acquiring signals in the hands. The algorithm presented has been tested in twelve subjects of different age and physical condition, obtaining a 99.7% of sensitivity and a 100 % of positive predictivity.
