Abstract

We elucidate how the heartbeat is controlled under various changes in mechanical environments. The ventricular model used here includes processes of the electrical rhythm, muscle contraction and the blood flow. They are coupled by mechanoelectrical feedback (MEF) as well as by excitation-contraction coupling. Our results show the diversity in dynamics of the heartbeat, various limit cycles and chaos. Under the condition of the generation of the limit cycle, the heartbeat is stable during changes in the venous pressure. We conclude that heartbeat is autonomously stabilized by self-organization of temporal coherence through MEF.
