May warrant BP adjustment in ejection time interpretation; leaves open clinical translation beyond physiologic determinants.
Does an increase in systemic arterial pressure prolong left ventricular ejection time in normal male subjects?
Steady-state increases in systemic arterial pressure prolong left ventricular ejection time, demonstrating that arterial pressure is a prime determinant of ejection time independent of stroke volume, heart rate, and inotropic state.
Shaver et al. (1968) studied this question.
