It is widely assumed that heartbeat dynamics are chaotic, although there has been no evidence confirming such an opinion, and some evidence to the contrary. Additionally, the deterministic assumptions of such dynamics cannot be demonstrated. An alternative model is presented based upon the notion of terminal dynamics, which can more faithfully represent key features of the heartbeat: namely, piecewise determinism, and singular points between beats, which allow for adaptability while maintaining stability.
人们普遍认为心跳动力学是混沌的，尽管尚无证据证实这一观点，反而有一些相反的证据。此外，这种动力学的确定性假设也无法得到证明。基于终态动力学的概念提出了一种替代模型，该模型可以更忠实地呈现心跳的关键特征：即分段确定性以及心跳之间的奇点，这些特征在保持稳定性的同时还具备适应性。
