目的分析心室颤动患者的动态心电图特点。方法对动态心电图监测过程中发生心室颤动的12例患者的动态心电图进行分析。结果12例患者中,11例心室颤动致猝死,1例心室颤动持续2min后自行终止。12例均为冠心病患者,动态心电图出现急性ST段抬高8例,急性ST段压低2例,长QT间期3例,高大U波1例。结论急性缺血是引发心室颤动致死的主要因素。
Objective To analyze the characteristics of ambulatory electrocardiogram in patients with ventricular fibrillation. Methods The dynamic electrocardiogram of 12 patients with ventricular fibrillation during the monitoring of ambulatory electrocardiogram was analyzed. Results Of the 12 patients, 11 died of ventricular fibrillation and 1 died of ventricular fibrillation after 2 minutes. All 12 patients had coronary heart disease. There were 8 cases of acute ST segment elevation in ambulatory electrocardiogram, 2 cases of acute ST segment depression, 3 cases of long QT interval and 1 case of high U wave. Conclusion Acute ischemia is the main factor leading to ventricular fibrillation.
