摘　　要：心率减速力不仅在心肌梗死后患者死亡风险分层方面有突出的临床价值,在其他方面的研究也逐渐展开。对心力衰竭患者,单变量相对危险回归分析显示,心率减速力在心因性死亡患者与存活患者中有统计学差异,并且通过适当康复锻炼可以改善;在电除颤后的持续性心房颤动患者中可以预测心房颤动的复发;在胰岛素依赖的2型糖尿病合并冠心病的患者中,包括心率减速力在内的严重的自主神经衰竭与左室射血分数和血糖控制不佳密切相关。此外,家庭式自主神经的自我检测可以通过短期的心率减速力检测实现等。Deceleration capacity（DC）was a valuable predictor of death risk stratification in the post myocardial infarction population.Otherwise,it was studied in many fields.It was reported that DC was significant different between the cardiac death and survivor of the heart failure patients by univariate proportional hazards regression analysis,and DC can be altered by exercise training.It was suggested that DC could predict early AF recurrence after electrical cardioversion.In patients with insulin-dependent type 2diabetes mellitus and coronary artery disease,presence of severe autonomic failure,defined as coincidence of abnormal heart rate turbulence and abnormal DC,associated with impaired LVEF and increased level of HbA1 C.Fuethermore,it was indicated that among healthy persons self-monitoring of short-term DC at home was feasible.
