目的探讨动态心电图监测在变异型心绞痛中的应用效果。方法选取2014年2月—2015年2月于鹰潭市人民医院就诊的变异型心绞痛患者68例,均行常规12导联心电图和Marquette Holter心电监测仪检查,观察并比较两种检查方法下患者ST段抬高、T波高耸、室性期前收缩等变化,观察患者的冠状动脉造影检查结果和ST段抬高情况。结果动态心电图检测对ST段抬高、T波高耸、室性期前收缩、房室传导阻滞、U波倒置、R波增高和S波降低、异常Q波检出率高于常规心电图,差异有统计学意义(P<0.05)。经冠状动脉造影检查,68例患者中10例患者无明显冠状动脉狭(14.71%),7例患者为重度狭窄(10.29%),36例患者为中度狭窄(52.94%),15例患者为轻度狭窄(22.06%)。共有65例患者显示有ST段抬高,抬高持续时间均超过1min。结论动态心电图监测在变异型心绞痛的诊断中具有较高的应用价值,能将患者心绞痛发作情况的全过程完整地记录下来。
Objective To investigate the effect of ambulatory electrocardiogram monitoring in variant angina pectoris. Methods Sixty-eight patients with variant angina who visited Yingtan People’s Hospital from February 2014 to February 2015 were enrolled in this study. All patients underwent routine 12-lead electrocardiogram and Marquette Holter monitor. ST-segment elevation, T-wave towering, ventricular contraction and other changes were observed in patients with coronary angiography and ST-segment elevation results. Results Holter detection of ST segment elevation, T wave towering, ventricular contraction, atrioventricular block, U wave inversion, R wave increased and S wave decreased, abnormal Q wave detection rate higher than conventional ECG, the difference There was statistical significance (P <0.05). Coronary angiography showed that 10 of 68 patients had no obvious narrowing of coronary artery (14.71%), 7 had severe stenosis (10.29%), 36 had moderate stenosis (52.94%), 15 had Mild stenosis (22.06%). A total of 65 patients showed an elevation of ST segment elevation lasting more than 1 min. Conclusion Holter monitoring has a high value in the diagnosis of variant angina and can record the whole process of angina pectoris completely.
