Resumen
The auscultation of the heart is still the first basic analysis tool used to evaluate the functional state of the
heart, as well as the first indicator used to submit the patient to a cardiologist. In order to improve the diagnosis
capabilities of auscultation, signal processing algorithms are currently being developed to assist the physician at
primary care centers for adult and pediatric population. A basic task for the diagnosis from the phonocardiogram
is to detect the events (main and additional sounds, murmurs and clicks) present in the cardiac cycle. This is
usually made by applying a threshold and detecting the events that are bigger than the threshold. However,
this method usually does not allow the detection of the main sounds when additional sounds and murmurs
exist, or it may join several events into a unique one. In this paper we present a reliable method to detect
the events present in the phonocardiogram, even in the presence of heart murmurs or additional sounds. ...
