  • Method and apparatus for noninvasive monitoring dynamic cardiac performance
    Patent number: 4993420
    Abstract: A method and apparatus for monitoring the cardiac output of living subjects. Carotid pulse waveforms and femoral pulse waveforms are measured and converted to digitized signals. The carotid pulse signal or waveform is applied as a voltage to the simulated aorta circuit and the circuit component values varied to develop a waveform output best matching the femoral pulse electrical waveform.
