[Heterometric self-regulation of the heart as a correlation of Starling's and Anrep's phenomena].
It is postulated that heterometric autoregulation of cardiac contractility mostly presents a combination of Starling's mechanism, including venous preload-length and length-shortening relations, and Anrep's phenomenon, comprising aortal postload-length and length-tension relations. It is propounded that Anrep's mechanism modulates the efficacy of Starling's mechanism ensuring the autoregulatory maintenance of the optimal average aortal pressure. Thus, the latter is both mediator and ultimate goal of the heterometric autoregulation of the heart.
