Abstract

This article introduces a method for constructing a heart-beat signal from a long record of phonocardiogram (PCG). The method comprises a series of algorithms that decompose a long data record of heart sound to its heart-beat cycles using the simultaneously recorded electrocardiogram (ECG). First the cardiac cycles are identified using the synchronized ECG signal. The corresponding heart-beat cycles are then extracted from the PCG signal and used to construct a template signal. Using the correlation of the heart-beat signals with the template signal, the heart- corrupted by noise are identified and discarded. The remaining heart-beats are then used to construct a heart-beat signal which is free of artefacts and can be used for various heart sound analysis purposes.
