　　[摘要] 目的觀察分析阴虚风动证室性早搏患者动态心电图的特征性改变。方法选取2011年11月～2016年8月于中国中医科学院广安门医院（以下简称“我院”）就诊的室性早搏之阴虚风动证患者90例作为室早组，并选取我院同期健康体检者30名作为对照组。所有受试者均行24 h动态心电图检查，观察分析两组患者的平均心率、最慢心率、心率变异性（HRV）指标、室早组患者昼夜室早频次、室早组患者中医证候分级与HRV指标的相关性。结果室早组的平均心率、最慢心率均高于对照组（P < 0.05）；室早组全部窦性心搏R-R间期的标准差（SDNN）、每5分钟节段的正常R-R间期平均值标准差（SDANN）、两个相邻的R-R间期差值>50 ms心率总数占全部分析信息期间内的心率数的百分比例（PNN50）、24 h连续正常的 R-R间期差值均方的平方根（RMSSD）、HRV三角指数值均低于对照组（P < 0.05）；室早组患者夜间的室性早搏频次高于昼间（P < 0.05）；室早组患者中医证候分级与年龄呈正相关，与SDNN、SDANN、PNN50、RMSSD、HRV三角指数均呈负相关。结论室早组患者的室早频次夜间高于昼间，且HRV值低于对照组，推测阴虚风动证室性早搏的发生与自主神经功能紊乱相关，且以迷走神经功能降低为主。

　　[Abstract] Objective To observe the characteristic changes of dynamic electrocardiogram in patients who were diagnosed as premature ventricular contractions with syndromes of stirring wind due to yin deficiency. Methods From November 2011 to August 2016， 90 patients who were diagnosed as premature ventricular contractions with syndromes of stirring wind due to yin deficiency in Guang"anmen Hospital， China Academy of Chinese Medical Sciences （“our hospital” for short） were selected as the premature ventricular contraction group， and 30 healthy subjects in our hospital were selected as the control group. All subjects underwent 24 hours dynamic electrocardiogram. The average heart rate， slowest heart rate， heart rate variability （HRV） of the two groups and the number of premature ventricular contraction in morning and night of premature ventricular contraction group， the correlation between TCM syndrome classification and HRV index in the premature ventricular contraction group were observed and analyzed. Results The levels of the average heart rate and the slowest heart rate in premature ventricular contraction group were all higher than those in control group （P < 0.05）. The levels of standard deviation of NN intervals （SDNN）， standard deviation of average 5 min NN intervals （SDANN）， percentage of differences exceeding 50 ms between adjacent normal number of intervals （PNN50）， square root of the mean squared differences of successive RR interval （RMSSD） and HRV trigonometric index in premature ventricular contraction group were lower than those in control group （P < 0.05）. The premature ventricular contraction frequency of premature ventricular contraction group in the night was more than that in the morning （P < 0.05）. The syndrome classification of traditional Chinese medicine in premature ventricular contraction group was positively correlated with age， which was negatively correlated with SDNN， SDANN， PNN50， RMSSD， HRV triangular index. Conclusion The premature ventricular contraction frequency of patients in premature ventricular contraction group in the night is more than that in the morning， and the HRV is lower than control group. It is speculated that the occurrence of premature ventricular contraction with syndrome of stirring wind due to yin deficiency is positively related to autonomic nerve dysfunction， mainly vagus function decline.
