Minimal oxygen cost of relaxation supports tension-time index primacy; leaves open human translation.
This study demonstrates that myocardial oxygen consumption is largely determined by the time peak systolic pressure is reached, with minimal oxygen cost associated with ventricular relaxation.
R. GRIER MONROE (1964) studied this question.
