变异性心绞痛采用12导联动态心电图同步记录诊断的临床价值分析

摘要

Objective:To explore the clinical value of 12-lead ambulatory electrocardiogram in the diagnosis of variant angina pectoris.Methods:96 cases of patients with variant angina pectoris treated were diagnosed with conventional electrocardiogram and 12-lead ambulatory electrocardiogram,the duration of angina pectoris attacking and times by the two methods were compared. Results:Variant angina pectoris mainly occurred in wee hours and at night.The detection rate of ST segment elevation,ventricular premature beat,U type inverted,T wave towering,atrioventricular block and abnormal Q wave in patients with variant angina pectoris by 12-lead ambulatory electrocardiogram were higher than that of conventional electrocardiogram(P<0.05 or P<0.01). Conclusion:12-lead ambulatory electrocardiogram in the diagnosis of variant angina pectoris had remarkable effect,which could record the attack process of variant angina pectoris perfectly and had big advantage compared with the conventional electrocardiogram.%目的：探讨变异性心绞痛应用12导联动态心电图同步记录诊断的临床价值。方法：收治变异性心绞痛患者96例，所有患者均采用常规心电图和12导联动态心电图诊断，比较两种方法心绞痛的发作时间和次数。结果：变异性心绞痛主要发生在凌晨和夜间。12导联动态心电图对变异性心绞痛患者ST段抬高、室性早搏、U型倒置、T波高耸、房室传导阻滞和异常Q波的检出率均高于常规心电图(P＜0.05或P＜0.01)。结论：12导联动态心电图诊断变异性心绞痛效果显著，能完整地记录出变异性心绞痛的发作过程，与常规心电图相比具有较大优势。
