Studies on the first derivative of the ventricular pressure pulse in man.

Abstract

The rate at which the ventricular pressure rises has been of interest to investigators for many years (1, 2). Wiggers demonstrated that when ventricular end-diastolic filling pressure was elevated by increasing the venous return to the heart or the resistance to ventricular ejection, the rate of rise of ventricular pressure also increased (3).
