Abstract
Two tubular, segmented hearts propel blood through the closed circulatory system of the medicinal leech and switch every 20-40 beats between two constriction patterns. We showed recently that within one heartbeat cycle, heart segments on one side constrict peristaltically rear-to-front (;peristaltic heart'), followed by nearly synchronous front-to-rear constrictions in the contralateral heart segments (;synchronous heart'). Using optical recordings from intact leeches, we now characterize the hemodynamic properties of the cardiac cycl
