目的:分析扩张型心肌病(DCM)的心电图改变,为临床诊断治疗提供依据。方法:回顾分析78例≤50岁DCM患者的心电图资料,总结DCM心电图特点。结果:DCM患者的心电图均有异常,其中以心律失常最多见(77.5%),其他依次为ST—T改变(70%),传导阻滞(45%),房室肥大(40%),异常Q波(30%),低电压(10%)等。结论:DCM有多种心电图表现,其多发、多样、顽固的心律失常对扩张型心肌病早期诊断有重要意义。
Objective: To analyze the changes of electrocardiogram in dilated cardiomyopathy (DCM) and provide the basis for clinical diagnosis and treatment. Methods: The electrocardiogram data of 78 patients with DCM ≤50 years were retrospectively analyzed to summarize the characteristics of DCM electrocardiogram. Results: The electrocardiogram of patients with DCM were abnormal. Among them, the most frequent was arrhythmia (77.5%), followed by ST-T change (70%), conduction block (45%), atrioventricular hypertrophy Q wave (30%), low voltage (10%) and so on. Conclusion: DCM has a variety of ECG manifestations, its multiple, diverse and stubborn arrhythmia in the early diagnosis of dilated cardiomyopathy is important.
