Abstract: We explore the rate-dependent dynamic response of periodically paced bullfrog (Rana catesbeiana) cardiac muscle. Alternans (2:2 behavior) occur in 35% of animals and 2:1<-->1:1 bistability in 74% of animals. In addition, we observe 2:2<-->2:1 bistablility. We discuss the implications of these results for two map-based models of cardiac dynamics. The high prevalence of bistability suggests that this dynamical behavior must be accounted for in the design of closed-loop feedback protocols to stabilize cardiac dynamics. © 1999 The American Physical Society.
