ABSTRACT:
An apparatus and method for sensing cardiac performance by providing real time values of left ventricular performance of ambulatory or inactive subjects. Noninvasive sensors such as noise reducing phonocardiographic sensors, multi-crystal piezoelectric doppler pulse wave sensors, volume oscillometric pulse wave sensors, and electrocardiographic sensors develop a plurality of electrical signals representing certain key physiological functions. These electrical signals are uniquely conditioned and combined by a central processing unit and associated programs to yield real time outputs of Left Ventricular Ejection Time, Systolic Time Interval and Ejection Fraction for either ambulatory or inactive patients. These values are displayed, along with analog patient cardiac-based waveforms, on a recording device and may be used for future play-back.
