Title
(EN) BALLISTOCARDIOGRAM ANALYSIS METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF D'ANALYSE DE BALLISTOCARDIOGRAMME
Abstract
(EN)
The present invention discloses a method and signal processing device (620) for analyzing a ballistocardiogram (BCG). The actual energy content of the cardiac part of the BCG in a predefined time window is determined and compared with a reference value. A difference between the actual energy content and the reference energy content exceeding a predefined threshold is indicative of the presence of an arrhythmia in the evaluated part of the BCG because the force exerted by an arrhythmic ventricular contraction, if at all present, is typically substantially smaller than the force exerted by a ventricular contraction of a regular heartbeat. This insight facilitates a more accurate detection of the presence of arrhythmias in a BCG compared to BCG detection schemes based on a heart rate analysis.

La présente invention porte sur un procédé et sur un dispositif de traitement de signal (620) pour analyse d'un ballistocardiogramme (BCG). Le procédé consiste à déterminer la teneur en énergie réelle de la partie cardiaque du BCG dans une fenêtre de temps prédéfinie et à la comparer à une valeur de référence. Une différence entre la teneur en énergie réelle et la teneur en énergie de référence supérieure un seuil prédéfini est indicative de la présence d'une arythmie dans la partie évaluée du BCG puisque, typiquement, la force exercée par contraction ventriculaire arythmique est sensiblement inférieure à la force exercée par contraction ventriculaire régulière. Comparée à des schémas de détection de BCG au moyen d’une analyse de la fréquence cardiaque, cette intuition facilite une détection plus précise d'arythmie dans un BCG.
