目的探讨动态心电图和常规心电图对变异型心绞痛患者的诊断价值.方法 80例变异型心绞痛患者应用常规心电图(ECG)和24 h动态心电图(DCG)检测,并对两种方法进行比较.结果损伤型ST段抬高伴对应导联T段下移,T波高耸对应导联T波倒置或低平,室性期前收缩、加速性室性逸搏、房室传导阻滞、巨型U波、R波倒置检出率比较,DCG明显高于ECG(P＜0.05).心电图异常发作高峰时间在0:00 ～ 8:00.结论动态心电图明显提高了对变异型心绞痛的检出率,对临床诊断和治疗有更重要的指导性意义.

Objective To investigate the diagnostic value by routine etectrocardiagram and dynamic electrocardiogram in patients with variant angina.Methods Conventional ECG and 24 h Holter test were performed and the results were compared in 80 patients with variant angina.Results Injurytype ST-segment elevation with the corresponding ST-segment depression,T-wave inversion or flattening in high-am-plitude T-wave corresponding lead,ventricular premature contraction,accelerated idioventricular rhythm,atrioventricular conduction block,giant R-wave and U-wave inversion,the detection rates of these abnormal ECG patierns were obversiouly higher than ECG.There was a significant difference (P ＜0.05).The peak time for the ECG abnormalities onset of variant angina was 00:00-08:00.Conclusions Dynamic ECG can show the whole process of variant angina,therefore it has a great value for guiding the diagnostic rate of variant angina.
