摘要
本文对166例冠心病患者进行24小时动态心电图分析,结果表明,动态心电图检出心律失常308例次(93.9%)而常规心电图检出34例次(20.4%),二者有显著差别(P<0.01)。166例动态心电图检出 ST-T 阳性64例(39.1%),常规心电图检出 ST-T 阳性5例(3%)。其中41例冠心病动态心电图与平板运动试验对比,两项结果一致者25例(60.9%)。11例平板运动试验阳性而动态心电图阴性,5例动态心电图阳性而平板运动试验阴性,两者同时进行可提高冠心病的检出率。动态心电图能检出有心绞痛发作和无症状患者的 ST-T 改变,检查方法简便,有较高的安全性值得推广。
The results of 24 hour ambulatory monitoring electrocardiography in 166 patientswith coronary heart disease were analysed.308 episodes(93.9%)of arrhythmiawere detected,while only 34 episodes(20.4%)were discovered in routine 12-leadelectrocardiography(P<0.01).64 patients(39.1%)were demonstrated positive ST-T,in contrast with 5 positive ST-T(3%)in routine electrocardiography.41 of the 166patients were compared with treadmill exercise testing.25 patients(60.9%)had theidentical results,eleven patients had the positive results in treadmill exercise testingbut negative in ambulatory electrocardiography.5 patients were positive in ambulatorybut negative in treadmill exercise testing.By combining both methods,more dpportu-nities to diagnose coronary heart disease could be attained.With ambulatory elec-trocardiography,the onset of angina pectoris and ST-T changes without symptomscould be detected.This method is worth recommended owing to its simplicity andsafety.
