1036例正常孕妇妊娠期心电图异常的初步分析

Analysis of the incidence and cause of abnormal ECG in normal pregnant women

目的探讨无器质性心脏病患者妊娠期间心电图异常的发生率，分析产生的机制和临床意义。方法对复旦大学附属妇产科医院2015年2月～3月间进行产科检查的1036例正常孕妇心电图进行回顾性分析，分析异常心电图的发生率和病因。结果妊娠期发生心电图异常者占25%。窦性心动过速占16.31%，短P-R间期占3.57%，T波改变与ST改变分别占1.93%和0.68%，室性期前收缩和房性期前收缩分别占1.16%和0.58%，少见的还有窦性心动过缓和房室传导阻滞等。各年龄组异常心电图类型的分布无明显差别。结论妊娠期间心电图异常的发生率较高，其中以窦性心动过速最为常见，其次为短P-R间期、T波改变和室性期前收缩，ST段改变和房性期前收缩亦为常见。

Objective Investigated the incidence of abnormal electrocardiogram(ECG)in patients without organic heart disease,and analyzed the mechanism and clinical significance.Methods A retrospective analysis was done for1036pregnant women's ECG in the affiliated obstetrics and Gynecology Hospital of Fudan University during February and March of2015.Results The abnormal ECG patients during pregnancy accounted for25%.Among all the ECG abnormalities,sinus tachycardia was16.31%,short PR interval was3.57%,T-wave change was1.93%,ST segment change was0.68%,premature ventricular contraction and atrial premature beat were1.16%and0.58%,respectively.And they also included a few patients with sinus bradycardia and atrio-ventricular block.There are no significant differences for the distribution of the types of abnormal ECG for all ages.Conclusion There is a higher incidence of ECG abnormalities during pregnancy.The sinus tachycardia is the most common happened,followed by a short PR,T wave changes and ventricular premature beat,ST segment changes and atrial premature beat.
