摘要
目的探讨非特异性心室内传导障碍的心电图特点及与疾病的相关性。方法回顾性分析71例非特异性心室内传导障碍的表现形式与年龄结构、疾病的关系。结果非特异性心室内传导障碍发生的男女比例为65∶6;在3个年龄组(10～39岁、40～59岁及60岁以上)的病例分别为23例(32%)、21例(30%)及27例(38%);单纯性特异性室内阻滞的发生率为35%、33%及30%;40岁以下组,无器质性心脏疾患及正常人占78%;60岁以上组,高血压、冠心病人群占59%;非特异性心室内传导障碍合并ST-T改变多见于器质性心脏病患者,占59%。结论非特异性心室内传导障碍的发生无年龄差别,但多见于男性患者。年轻人群中,非特异性心室内传导障碍常见于无器质性心脏疾患及正常人;老年人病因以高血压、冠心病为主。非特异性心室内传导障碍合并其他心电图异常时临床意义较大。
Objective To explore the electrocardiogram （ECG） signal of non-specific intravent- ricular block and the correlation with disease. Methods Analysis retrospectively ECG signals of 71 pa- tients with non-specific intraventricular block at different ages, and the relationship with disease. Results Non-specific intraventricular conduction block occurred in the sex ratio of 65 ： 6 （ male to female）. Inci- dence at three ages was 32% , 30% , 38% respectively. In the group less than 40-year-old, the main population was without organic heart disease patients and health people （78%）. More than 60-year-old, the main cause was coronary heart disease （CHD） and hypertension （59%）. Non-specific intraventricu- lar block with ST-T variation is common in patients with organic heart disease （59%）. Conclusions There was no difference of incidence at three ages, but is common in male patients. In younger patients, non-specific intraventricular block is common in patients without organic heart disease and healthy people, however, in elders, the pathogeny is mainly hypertension or CHD （coronary heart disease）. There is larger clinical significance when nonspecific intraventricular conduction block is combined with other ECG abnormalities.
