Evidence is presented supporting the hypothesis that the positive inotropic effect after an abrupt increase in systolic pressure anrep effect is the recovery from subendocardial ischemia induced by the increase and. The anrep effect is an autoregulation method in which myocardial contractility increases with. An evaluation of the effect of khellin on the pulmonary. It was experimentally determined that increasing afterload caused a proportional linear increase in ventricular inotropy this effect is found in denervated heart preparations, such as the starling preparation, and as such, represents an intrinsic autoregulation mechanism.
