目的分析扩张型心肌病心律失常临床特点。方法对68例扩张型心肌病患者进行12导心电图、动态心电图、超声心动图、心血管X片检查。结果68例扩张型心肌病患者心律失常检出率100%,室性心律失常占76.5%,最多。房性心律失常占58.8%,传导阻滞38例,占55.7%。结论左房内径≥45 mm与心房颤动有相关性,左室射血分数、左室舒张期内径与恶性室性心律失常有相关性,病程与严重心律失常发生率无相关性。
Objective To analyze the clinical features of arrhythmia of dilated cardiomyopathy. Methods Sixty-eight patients with dilated cardiomyopathy underwent 12-lead ECG, Holter, echocardiography and cardiovascular X-ray examination. Results 68 cases of dilated cardiomyopathy patients detected 100% arrhythmia, ventricular arrhythmia accounted for 76.5%, the largest. Atrial arrhythmias accounted for 58.8%, conduction block in 38 cases, accounting for 55.7%. Conclusions There is a correlation between left atrial diameter ≥45 mm and atrial fibrillation. There is a correlation between left ventricular ejection fraction, diastolic diameter of left ventricle and malignant ventricular arrhythmia. There is no correlation between course of disease and incidence of severe arrhythmia.
