扩张型心肌病心律失常60例分析

目的探讨扩张型心肌病心律失常的相关因素。方法扩张型心肌病患60例，对比分析超声心动图与24h 12导联动态心电图。结果房性心律失常组较非房性心律失常组左心房明显扩大（P〈0．01），传导阻滞组较非传导阻滞组左心室明显扩大（P〈0．05），复杂（或恶性）室性心律失常组较非复杂（或恶性）室性心律失常组左心室明显增大（P〈0．05）。结论扩张型心肌病并发房性心律失常与心房扩大有关，传导阻滞的发生与左心室扩大有关，复杂（或恶性）室性心律失常的发生与左心室扩大有关。

Analysis of 60 cases with dilated cardiomyopathy with arrhythmia

Objective To study the relevant factors of arrhythmia of dilated cardiomyopathy. Method Compared and analysed 12-lead ambulatory electrocardiogram(Holter) and echocardiogram of 60 patients with dilated cardiomyopathy. Results The atrial enlargement in atrial arrhythmia group increased more obviously than non-atrial arrhythmia group(P<0.01). The ventricular enlargement in conduction blockade group increased more obviously than non-conduction blockade group(P<0.05). Conclusion The emergence of atrial arrhythmia is closely related to atrial enlargement. The conduction blockade related to enlargement of left ventricle.The ventricular arrhythmia probably had no correlation to enlargement of left ventricle.
