摘要：目的：探讨扩张型心肌病发生心律失常的类型及原因，加深对本病的认识。方法：回顾分析106例扩张型心肌病心律失常的发生率、类型以及与心功能、房室大小的关系。结果：其心律失常发生率92.7%，以传导阻滞占首位，占心律失常68.5%，其次为室性心律失常，占心律失常65.1%，且室性心律失常的发生与左室扩大有关(P<0.05)。心房颤动的发生与左房扩大有关(P<0.01)。结论:扩张型心肌病的心律失常发生率高，且多样易变，其发生与广泛心肌纤维化致心电生理异常，影响心肌细胞的电传导和自律性有关。

    Abstract: Objective: To study the type and causes of dilated cardiomyopathy with arrhythmia. Method: We reviewed the occurrence rate type and heart function, artrioventricular in 106 cases dilated cardiomyopathy with arrhythmia. Result: The rate of arrhythmia is 92.7%. During all the cases. The AVB and ventricular arrhythmia is 68.5% and 65.1% respectively. There's relationship between ventricular arrhythmia and left ventricular dilated(P<0.05). The atrial fibrillation if related with left atrial dilated(P<0.01). Conclusion: The dilated cardiomyopathy with arrhythmia is variable and related with cardiac electrophy siological abnormality resulted from myocardial fibrosis and then affect myocardiod cell electic conduction and automaticity. ......
