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.
Claims18
A method of determining cardiac time intervals of a patient, the method comprising:
- measuring arterial pulse values over time;
- generating left ventricular waveform data based on the arterial pulse values;
- identifying main cardiac events based on the left ventricular waveform data;
- and
- deriving systolic and diastolic time intervals based on the main cardiac events.
