Abstract

Phonocardiogram (PCG) and Electrocardiogram (ECG) are the two important signals for cardiac preliminary diagnosis. Using ECG as a reference for segmenting the PCG signal is a simple but reliable technique for the devices with integration capability of PCG and ECG recording. The aim of this work is to analyse the time delay between ECG and PCG at each auscultation site. To do so, we performed the experiments on 12 healthy subjects, where the ECG and PCG signals were collected simultaneously at two sites at each time. Our results reveal that 1) the inter-distance of the electrodes for ECG does not affect the occurrence time of the R-peak. 2) The delay between R-peak and onset of first heart sound (S1) depends on the auscultation site e.g. S1 onset occurs before the R-peak at auscultation site M. This study suggests that small integrated ECG-PCG devices can be made by reducing the distance between the ECG electrodes. In the meantime, distinguishing the auscultation location is necessary for performing more precise PCG segmentation using ECG as reference.
