八十年代以来，人们用非线性动力学的方法对心脏活动进行了很多的研究，取得了不少研究成果。这方面的研究目前受到国内外学者越来越多的关注，有着良好的发展前景，对研究心脏活动、揭示病变机理和早期诊断心脏疾病具有重要的意义。本文对近年来用非线性动力学理论研究心率变异、心电信息、心肌活动、心肌细胞中离子流活动和心脏中混沌运动的控制等方面的工作做一评述，并介绍了我们近来在这方面的研究结果 Since the 1980s, people have done a lot of research on heart activity using the method of nonlinear dynamics, and have made a lot of research achievements. At present, the research in this field has drawn more and more attention from scholars both at home and abroad, and has a good prospect of development. It is of great significance to studying cardiac activity, revealing the pathological mechanism and early diagnosis of heart disease. In this paper, we review the recent work on the nonlinear dynamics theory of heart rate variability, ECG information, myocardial activity, ion current in cardiomyocytes and the control of chaos in the heart. We also present our recent work in this area The results of the study
