A non-invasive cardiac monitoring device for calculating the cardiac performance parameters of heartbeat, stroke volume, and cardiac output for an individual. The device receives a plurality of electrocardiogram waveform signals from the individual and selects the R-wave component having the maximum value of the electrocardiogram waveform signals and the T-wave component having the maximum value of the electrocardiogram waveforms. From these values, the stroke volume of the individual and the cardiac output of the individual may be calculated according to the equation: Stroke Volume = 6 x R(max.)/T(max.) + 26Ø The periodicity of subsequent electrocardiogram waveforms are utilized to calculate the cardiac performance of the individual.
On décrit un appareil de mesure cardiaque de caractère non invasif permettant de déterminer les paramètres suivants chez une personne : le rythme cardiaque, le volume sanguin pulsé et la performance cardiaque. L'appareil enregistre plusieurs traces électrocardiographiques et en extrait l'onde R maximale ainsi que l'onde T maximale. partir de ces valeurs, on peut déduire le volume sanguin pulsé ainsi que la performance cardiaque de l'individu à l'aide de l'équation : Volume sanguin pulsé = 6 * R(max)/T(max) + 26,0. La périodicité des traces électrocardiographiques subséquentes permet de déterminer la performance cardiaque.
