Title
(EN) METHOD AND APPARATUS FOR DETERMINING INFORMATION INDICATIVE OF CARDIAC MALFUNCTIONS AND ABNORMALITIES
(FR) PROCÉDÉ ET APPAREIL POUR DÉTERMINER DES INFORMATIONS FAISANT ÉTAT DE DYSFONCTIONNEMENTS ET D'ANOMALIES CARDIAQUES
Abstract
(EN)
An apparatus for determining information indicative of cardiac malfunctions and abnormalities comprises a processing device (402) configured to extract, from a signal indicative of electromagnetic phenomena related to cardiac activity, a first wave pattern repeating on a heart-beat rate and, from a signal indicative of cardiovascular motion, a second wave pattern repeating on the heart-beat rate. The processing device is configured to form timing data such that each timing value of the timing data is indicative of a time period from a reference point of the first wave pattern belonging to one heart-beat period to a reference point of the second wave pattern belonging to the same heart-beat period. The processing device is configured to determine, at least partly on the basis of the timing data, an indicator of cardiac malfunction and abnormality. The figure proposed to be presented with the abstract:

Appareil servant à déterminer des informations faisant état de dysfonctionnements et d'anomalies cardiaques, comprenant un dispositif de traitement (402) conçu pour extraire, à partir d'un signal indiquant des phénomènes électromagnétiques liés à l'activité cardiaque, un premier motif d'onde se répétant sur une fréquence cardiaque et, à partir d'un signal indiquant un mouvement cardiovasculaire, un second motif d'onde se répétant sur la fréquence cardiaque. Ce dispositif de traitement est conçu pour former des données de synchronisation de telle sorte que chaque valeur de synchronisation des données de synchronisation indique une période de temps comprise entre un point de référence du premier motif d'onde appartenant à une période cardiaque et un point de référence du second motif d'onde appartenant à la même période cardiaque. Ce dispositif de traitement est conçu pour déterminer, au moins en partie sur la base des données de synchronisation, un indicateur d'un dysfonctionnement et d'une anomalie cardiaque.
