Abstract

The heart auscultation is the main investigation approach used to evaluate the possibility of a diseases. In order to improve the automatic diagnosis capabilities of auscultations, signal processing algorithms are developed. A basic task for the diseases diagnosis from the phonocardiogram is to detect the exact timing location of the events presents in the cardiac cycle, especially in pathological cases. In this paper is presented a new technique for segmentation and identification of cardiac sounds able to operate even in the case of cardiac anomalies, and without any additional reference signal such as electrocardiogram signal. A framework to arrhythmias detection based on the heart rate variability, is presented. The advantage in term of low computational burden inherited from the characteristics of fuzzy logic has been tested with a set of normal and abnormal heart sounds achieving satisfactory results.
