ABSTRACT:
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 electrocardiogram waveform signals from the individual and calculates a ratio of the R-wave component of the electrocardiogram waveform to the T-wave of the electrocardiogram waveform. From this ratio, the stroke volume of the individual and the cardiac output of the individual may be calculated. The periodicity of subsequent electrocardiogram waveforms are utilized to calculate the heartbeat of the individual.
