In brief: DPTI
It is a measure of coronary blood supply.
Multiply the coronary perfusion pressure times the diastolic tmie. Cpp =diastollic blood pressure minus the left vetricular end diastolic pressure. Diastolic time is 60sec/heart rate-0.2seconds. The 0.2 is systolic time(fixed at 0.2s). Coronary flow occurs during diastole and relates to the pressure and how long diastole lasts. Now ask me what the evr is.

In brief: Coronary blood flow
It is a measure of how much blood flow is going through the coronary arteries (arteries that feed the heart muscle).
