Abstract
A method and apparatus for determining cardiac time intervals that can measure physiological data noninvasively. Arterial pulse values are measured either invasively or noninvasively, from which left ventricular waveform data is generated. Systolic and diastolic time intervals are derived based on the left ventricular waveform data.
