Abstract
La présente invention concerne un signal sonore auscultatoire provenant d'au moins un capteur de vibration ou de son auscultatoire segmenté en une pluralité de segments de cycle cardiaque associés en réponse à des emplacements de pic R associés d'un signal d'enveloppe électrographique représentant une réponse d'enveloppe à une puissance uniforme d'un signal électrographique associé provenant d'un capteur d'ECG. Une représentation d'une enveloppe sensible à une puissance uniforme dudit signal sonore auscultatoire dans ledit au moins un cycle cardiaque est modélisée localement autour d'au moins un second pic pour permettre la localisation du début de la diastole dudit au moins un cycle cardiaque.
