Title: METHOD FOR DETERMINING AT LEAST A CARDIAC STRESS DURATION AND/OR A CARDIAC RECOVERY DURATION FROM A HEARTBEAT SIGNAL
Abstract:
In a method for determining, in particular continuously, at least a cardiac stress duration and/or cardiac recovery duration and, preferably, a cardiac stress quotient and/or a cardiac recovery quotient from a heartbeat signal, in particular from an electrocardiogram (3) and/or a magnetocardiogram and/or an impedance cardiogram and/or a ballistocardiogram and/or a seismocardiogram and/or a phonocardiogram, it is proposed that a heartbeat signal is recorded from a human or animal subject, wherein, subsequently from the heartbeat signal, at least an atrial contraction duration and/or a ventricular contraction duration and/or an atrioventricular contraction duration is determined as cardiac stress duration and/or an atrial dilatation duration and/or a ventricular dilatation duration and/or an atrioventricular dilatation duration is determined as cardiac recovery duration.
