目的探究动态心电图监测变异性心绞痛的临床价值。方法选取变异性心绞痛患者62例,采用常规12导联心电图检查及动态心电图检查,比较两种方法的诊断结果。结果动态心电图检查对S波降低、室性早搏、T波高耸、房室传导阻滞、ST段抬高、U波倒置、异型Q波及R波增高的检出率,显著高于常规心电图检查,差异有统计学意义(P<0.05)。结论采用动态心电图监测变异性心绞痛,准确性和安全性高,且操作简单,具有较高的临床诊断价值,值得临床推广和应用。
Objective To investigate the clinical value of Holter monitoring of variant angina pectoris. Methods Sixty-two patients with variant angina were selected. The routine 12-lead electrocardiogram and ambulatory electrocardiogram were used to compare the diagnostic results of the two methods. Results The detection rate of dynamic ECG on S wave, premature ventricular contraction, towering T wave, atrioventricular block, ST segment elevation, U wave inversion, abnormal Q wave and R wave increased significantly higher than conventional ECG, The difference was statistically significant (P <0.05). Conclusions The use of ambulatory electrocardiogram to monitor variant angina pectoris has the advantages of high accuracy and safety, simple operation and high clinical diagnostic value, which deserves clinical application and promotion.
