Key result
In a canine model, the onset of left ventricular relaxation during normal ejection occurred at 34 +/- 3% of systolic time and approximately 16% after the onset of ejection.

May delineate LV relaxation onset; leaves open clinical translation and prospective validation in humans.
Solomon et al. (1999) studied Left ventricular relaxation physiology (n=6). Aortic occlusions during systole vs. Control beat was evaluated on Onset of left ventricular relaxation (percentage of systolic time). In a canine model, the onset of left ventricular relaxation during normal ejection occurred at 34 +/- 3% of systolic time and approximately 16% after the onset of ejection.
