A method for instantaneous measurements and representations of myocardial pressure-velocity relations permitting the analysis of various contractility parameters is described. Basing on a modified two-element model of cardiac muscle the measurement of the relative shortening velocity vce = dp/dt(p) of the contractile elements is carried out by a special analog computer, which calculates the quotient (dp/dt) to the simultaneous left ventricular pressure p. Electronic differentiation of the… CONTINUE READING
