扩张型心肌病心电图分析

Analysis of the Electrocardiogram in Dilated Cardiomyopathy

目的:探讨扩张型心肌病患者心电图改变,为临床诊断、治疗及预后评估提供依据。方法:回顾性分析2000年1月至2008年12月间31例经心脏超声检查诊断为扩张型心肌病,并行24小时动态心电图监测患者的临床资料。结果:所有病例心电图均有异常改变。严重心律失常组的左室舒张末内径(LNED)及左室射血分数(LVEF)较非严重心律失常组明显增大,[69.47±7.65 mm & 61.92±4.80 mm,(31.37±5.73)%&(39.50±6.26)%],P<0.01;(2)房颤组的左房内径较非房颤组显著增大,(49.00±3.11 mm&39.88±2.36 mm),(P<0.01)。结论:扩张型心肌病患者心律失常发生率高,并且呈多样化,对出现严重心律失常、ST-T异常等改变的患者,有必要进行心脏超声检查。

Objective:To provide the basis in clinical diagnosis,treatment and prognostic evaluation by explored the abnormal changes of electrocardiogram of dilated cardiomyopathy(DCM). Methods: The clinical data of Holter of 31 patients with dilated cardiomyopathy confirmed by echocardiogram (UCG) was analyzed retrospectively from Jan 2000 to Dec 2008. Results:All cases had abnormal changes in ECG. The LVED and LVEF in serious arrhythmia group were significantly higher than those in nonserious arrhythmia group [69.47±7.65 mm &61.92±4.80 mm, (31.37±5.73)% & (39.50±6.26)%],P<0.01. Interior diameter of left atrium in atrial fibrillation group was significandy higher than that in nonatrial fibrillation group (49.00±3.11 & 39.88±2.36) ,P<0.01. Conclusions: The incidence of arrhythmia is high and the arrhythmia is variable in dilated cardiomyopathy.It is necessary to accept echocardiogram examination in patients with serious arrhythmia, abnormal changes of ST-T segment.
