据研究,室性心律失常特别是室性心动过速(VT),在主动脉瓣病患者的猝死中有重要作用.因这种心律失常可以严重影响心肌作工,引起左室机能的损害.作者报告4例主动脉瓣病患者心脏性猝死期间的动态心电图监测结果,发现室性心律失常是这些患者猝死的主要原因. 4例患者(3男、1女),平均年龄66±4岁,其中3例经心导管检查排除了冠心病确诊为主动脉瓣病,另1倒无冠心病史及冠心病易患因素,动态心电图监测无显著ST段改变。所有患者心脏功能Ⅲ或Ⅳ级(纽约心脏学会),3例有晕厥史,在室
According to the study, ventricular arrhythmias, particularly ventricular tachycardia (VT), play an important role in sudden death in patients with aortic valve disease, which can severely affect myocardial work and cause impairment of left ventricular function. The authors report the results of a dynamic electrocardiogram (ECG) study of 4 patients with aortic valve disease during sudden cardiac death and found that ventricular arrhythmias were the major causes of sudden death in these patients. Four patients (3 males and 1 female) with an average age of 66 ± 4 years, Three cases of cardiac catheterization ruled out coronary heart disease diagnosed as aortic valve disease, the other one had no history of coronary heart disease and coronary heart disease risk factors, ECG monitoring without significant ST segment changes. All patients had grade III or IV heart function (New York Heart Association), 3 had a history of syncope,
