Optimization of the position of single-lead wireless sensor with low electrodes separation distance for ECG-derived respiration

Abstract

ECG-Derived Respiration (EDR) is a classical method for estimation of respiratory information from Electrocardiogram (ECG). This method normally uses flexible electrodes located at standard electrocardiography positions. This study introduces an alternative approach suitable for miniaturized sensors with low inter-electrode separation and electrodes fixed to the sensor encapsulation. Application of EDR amplitude algorithm on a single-lead wireless sensor system with optimized electrode positions shows results comparable with standard robust systems. The modified method can be applied in daily physiological monitoring, in sleep research studies or it can be implemented in smart clothes when standard respiration techniques are not suitable. In this paper we report optimization of the positions of miniaturized device for measurement of ECG and ECG-derived respiration.
