短阵性房性心动过速动态心电图分析与探讨

189 Cases of Transient Antrum Pyknosphygmia Dynamic Electrocardiogram Analysis and Approach

目的对短阵性房性心动过速的发生规律进行研究并探讨其机制。方法应用24h动态心电图对1125例患者进行监测,并对其中发现短阵性房性心动过速189例642阵进行回顾性分析。结果642阵短阵性房性心动过速发生率为16.8%;且发生规律与生活状态有密切关系,迷走神经兴奋时发生率较高达64%;频率较慢,持续时间较短,患者多无症状。各年龄组短阵性房性心动过速的检出率经显著性检验差异显著(P<0.005),老年组检出率明显高于青年组。结论由于AECG检测时间长,易发现短阵性房性心动过速。AECG检出642阵短阵性房性心动过速中以迷走神经兴奋时发生率较高,是一种保护性心律失常。老年人出现的短阵性房性心动过速,尤其发生在迷走神经兴奋时,为一种常见现象,不需特殊治疗。

Objective Study the proceeding regularity of transient antrum pyknosphygmia and approach its proceeding mechanism. Methods Use 24 hours dynamic electrocardiogram monitoring 1125 patients, retrospective analysis 189 patients of 642 cases of transient antrum pyknosphygmia. Results 642 cases of transient antrum pyknosphygmia of incidence rate was 16.8%; the incidence rate was 64% when cranial nerve was excitement; When the frequency was slow and the duration time was short, the patients were without symptoms.The transient antrum pyknosphyg- mia detect rate of old group was higher than young （P〈0.005）. Conclusion The detect time of AECG was long, so patients were trend to proceed transient antrum pyknosphygmia. Incidence rate was higher when cranial nerve was excitement within 642 cases of transient antrum pyknosphygmia detect by AECG, it was a kind of conservancy unnormal heart rate. Transient antrum pyknosphygmia happened within old patients, especially within cranial nerve excitement, was a common phenomenon which need no special treatment.
