目的：分析室性心律失常患者的心率减速力（DC ），探讨其预测心律失常的价值。方法：对我院2012年1月到2015年7月门诊及住院患者的动态心电图（DCG ）资料进行回顾性分析。以DCG直接检出室性心动过速的41例康复患者为室速组，随机选择同期一般资料相仿，且无心动过速的37例患者为无心动过速组。所有入选者经DCG检测，计算得出DC ，并进行两组间比较。结果：以DC值＜4.5 ms为异常，＜2.5 ms为显著异常作为评判标准。与无心动过速组比较，室速组DC显著降低[（8.72±1.78） ms比（4.01±1.90） ms]， P＜0.01；DC异常率（5.41％比51.22％）和DC显著异常率（0比29.27％）均显著升高， P均＜0.01。结论：室性心动过速患者有较高的异常心率减速力检出率。心率减速力测定有益于预测心律失常和心源性猝死。

Objective:To analyze deceleration capacity of heart rate (DC) in patients with ventricular arrhythmia , and explore its predictive value for ventricular arrhythmia .Methods :Dynamic electrocardiogram (DCG) data of outpatients and inpatients ,who were treated in our hospital from Jan 2012 to Jul 2015 ,were retrospectively ana‐lyzed .A total of 41 rehabilitation patients with ventricular tachycardia (VT) directly detected by DCG were treated as VT group ,another 37 cases with similar general data and non‐tachycardia were enrolled as non‐tachycardia group in the same period .DCG was used to measure and calculate DC in all subjects , DC indexes were compared between two groups .Results:DC<4.5 ms was regarded as abnormal and DC<2.5 ms was regarded as significantly abnor‐mal .Compared with non-tachycardia group ,DC significantly reduced [ (8.72 ± 1.78) ms vs .(4.01 ± 1.90) ms] , P<0.01 ;there were significant rise in abnormal DC rate (5.41% vs .51.22% ) and significant abnormal DC rate (0 vs .29.27% ) in VT group , P<0.01 both .Conclusion:Detection rate of abnormal DC is high in VT patients .DC measurement is helpful for predicting ventricular arrhythmia and sudden cardiac death .
