Key result
Systolic time intervals provide a sensitive and easily measured assessment of left ventricular function that is well suited for studying the effects of pharmacologic agents on the heart.
Systolic time intervals provide a sensitive, easily measured method to assess left ventricular performance and the effects of pharmacologic agents.
Should not yet change clinical practice; extends literature supporting systolic time intervals for pharmacologic LV research.
The systolic time intervals (STI) offer temporal description of the sequential phases of cardiac cycle which are influenced physiologically by the same variables as affect other measures of left ventricular (LV) performance. The STI hence offer a measure of ventricular function which augments other measures of ventricular performance. Because of the extreme sensitivity of this variable and the ease of its measurement the STI are well suited for studying the effect of pharmacologic agents upon the heart.
