Abstract:

An automated method for a beat-to-beat analysis of Systolic Time Intervals STI has been developed using a unilateral hybrid computer system. Beat number, time of occurrence of beat, heart rate preejection period PEP, preejection period index PEPI, left ventricular ejection time LVEF, left ventricular ejection time index ETI, total electromechanical systole Q-S2, total electromechanical systole index Q-S2I, isovolumic contraction time IVCT, and ratio of PEP to LVET were calculated from simultaneous recordings of electrocardiogram, carotid pulse, and phonocardiogram. The ability of automated analysis to provide beat-to-beat values extends the usefulness of this noninvasive method to evaluate left ventricular performance. Author
