晚期孕妇短P-VR间期心电图有否引起心动过速诱发猝死潜在危险因素的研究

A Research of the relationship between the end stage pregnant women's short PR interval ECG and tachycardia which leads to potential dangerous factors of sudden death

目的探讨晚期孕妇短P-R间期心电图是否引起心动过速,诱发猝死潜在危险因素存在(如心房扑动、心房颤动、室性心动过速、心室颤动等)拟通过研究发现致命性危险因素,早期预警、早期临床介入,预防猝死的发生。方法回顾分析2009年5月～2010年6月共2160例晚孕孕妇12导联同步心电图。结果 68例出现短P-R间期,发生率为3.14%。此68例中有6例出现阵发性窦性心动过速,占8.82%。此6例心动过速孕妇的胎儿也同时发生心动过速。68例短P-R间期孕妇彩色多普勒心功能检查全部正常,无一例发生血流动力学改变。结论晚期孕妇短P-R间期可引发阵发性窦性心动过速并可诱发胎儿心动过速,但无心房扑动、心房颤动、室性心动过速、心室颤动等诱发猝死的潜在危险因素。

Objective To discuss whether the end stage pregnant women's short PR interval ECG would cause tachycardia which leads to sudden death,for the potential factors such as atrial flutter,atrial fibrllation,ventricular tachycardia,ventricular fibrillation,etc.This research aimed to find out those fatal dangerous elements in order to pre-warn and even intervene into the early clinic stage to prevent sudden death and save the pregnant women as well as their children. Methods 2,160 pieces of 12 chest lead ECG at of the end stage pregnant women from May,2009 to June,2010 were invetigaed. Results 68 pregnant women showed short PR interval ECG,accounting for 3.14%.Among the 68 examples,6 of them had sinus tachycardia,and the rate was 8.82%.At the same time,6 fetuses of the sinus tachycardia pregnant women were also sinus tachycardia,which shows there is a strong relationship between them.All the 68 pregnant women's ACM were normal,none of them had blood dynamic changes. Conclusion The end stage pregnant women's short PR interval ECG would cause sinus tachycardia and fetus tachycardia as well,but there are no potential dangerous factors such as atrial flutter,atrial fibrillation,ventricular tachycardia,ventricular fibrillation,etc.
