摘　　要：心肌梗死后由于迷走神经功能受到抑制,心脏负性频率调节能力下降而容易诱发心脏性猝死。通过自主神经功能检测可预测心肌梗死后心脏性猝死的发生。通过检测心率减速力和连续心率减速力,定量评价迷走神经张力的大小,可对猝死风险进行分层。国内外大量研究都高度肯定心率减速能力检测对心肌梗死后心脏性猝死的预警价值,该文就心率减速能力检测的方法、优越性及其对心肌梗死后猝死的预警价值予以简单综述。The function of vagus nerve was inhibited alter myocardial intarction, the inability ol heart ratedeceleration can easily lead to sudden cardiac death. So we can predict sudden cardiac death after myocardialinfarction through the detection of autonomic nerve function. Deceleration capacity of heart rate （ DC ） andheart rate deceleration runs（DRs） can evaluate the vagus nerve＇s activity, and different risk stratifiers aremade to predict sudden cardiac death. A number of domestic and foreign studies speak highly of DC and DRson predicting cardiac death after myocardial infarction. Here is to make a simple review of the detection meth-ods, advantages and predictive value of heart rate deceleration.
