双峰T波与先天性心脏病

Occurrence of bifid T wave in congenital heart disease

目的探讨先天性心脏病及正常人群组双峰T波的检出率差异性,年龄和性别对双峰T波检出率的影响。方法回顾性分析明确诊断为先天性心脏病例675例和680例健康者（对照组）的平静心电图,分析双峰T波在先天性心脏病中的检出率和在室间隔缺损（VSD）、房室间隔缺损（AVSD）、房间隔缺损（ASD）和法洛四联症（F4）患者中的检出率。结果①与对照组比较,先天性心脏病中出现双峰T波患者401例（检出率59.4%,p〈0.05）,其中,双峰T波在ASD中检出率42.1%,在VSD中检出率70.6%,AVSD双峰T波出现38例（82.2%）,在F4中出现率42.3%;检出圆顶尖角T波及尖角T波169例（检出率26.0%）;②随着年龄增长,先心病组及正常人群组双峰T波检出率降低;③正常人群组双峰T波检出率男性15岁左右开始逐渐下降,女性20-30岁检出率达高峰。结论双峰T波在先天性心脏病患者中检出率高于正常人;双峰T波受年龄的影响,正常人群还受性别的影响。

Objective To investigate the genesis and the clinical significance of the bifid T wave in congenital heart disease （CHD）. Methods ECG of 675 patients suffered from congenital heart disease and 680 healthy people were being retrospective analysis, then we studied occurrence rate of bifid T waves in CHD and further analyzed it occurred in patients who being attacked by ventricular septal defect（VSD）, atrioventricular septal defect（AVSD）; atrial septal defect（ASD） and tetralogy of Fallot（F4）. Results In contrast to control groups, bifid T waves occurred in 59.4% of 401 patients and occurrence rate of bifid T waves was 42.1%, 70.6%, 82.2%; 42.3 in ASD,VSD, AVSD and F4 respectively, ＂dome and dart＂, ＂in bifid T waves occurred in 26% of 169 patients. Bifid T waves was downed accompany by older. Conclusions Bifid T waves observed in CHD was more frequency than in healthy subjects, the observations suggest that the occurrence of bifid T waves effeeted on age and gender.
