<p>A system (10) non-invasively obtains a left-ventricular pressure waveform by acquiring pressure waveforms from first and second pressure measurements using a first group (12) of non-invasive pressure measurement devices. Selectors (70 and 72) each select a segment form each of the first and second pressure waveforms. Each segment is associated with a different interval of a cardiac cycle. The shifter (74) then time-shifts the segments by an amount indicative of a relative time of occurrence of each of the first and second segments.</p> |
