心电图检查对肥厚型心肌病的临床价值

目的探讨肥厚型心肌病患者心电图变化及其临床意义。方法56例肥厚型心肌病患者进行常规十二导心电图检查及超声心动图，对异常心电图进行统计分析，出现心律失常者加做动态心电图。结果正常心电图2例（3．6％），异常心电图54例（96.4％），异常心电图中以ST-T改变、左室高电压、异常Q波常见，并各自有其特点，其中ST-T改变50例（92．6％），左室高电压22例（40．7％），异常Q波20例（37．0％），心律失常中以室性早搏、房室传导阻滞及右束支传导阻滞最常见，其中室性早搏18例（33.3％），房室传导阻滞9例（16．7％），右束支传导阻滞7例（13．0％），房性早搏5例（9．3％），心房颤动3例（5．6％）。结论提高对肥厚型心肌病心电图特点的认识，结合超声心动图，可大大提高肥厚型心肌病的诊断准确性，减少误诊与漏诊。

The Clinical Significances of Electrocardiogram Examination in Patients with Hypertrophic Cardiomyopathy

Objeetive To investigate the clinical significance of electrocardiographic changes in patients with hypertrophic cardiomyopathy. Methods 56 cases of patients with hypertrophic cardiomyopathy examined by echocardiography and synchrony 12-leads electrocardiogram, analyzed abnormal electrocardiogram, arrhythmia with electrocardiogram plus dynamic electrocardiogram. Results Normal electrocardiogram 2 cases （3.6%）, abnormal electrocardiogram 54 cases （96.4%）, ST-T anomaly, left ventricular high voltage and abnormal Q wave are common in abnormal electrocardiogram, they have own characteristics. ST-T anomaly 50 cases （92.6%）, left ventricular high voltage 22 cases（40.7%）, abnormal Q wave 20 cases （37.0%）. Ventrial premature beats, atrioventricular block and right bundle branch block are common in arrhythmia with electrocardiogram, ventricular premature beats 18 cases （33.3%）, atrioventricular block 9 cases （16.7%）, right bundle branch block 7 cases （13.0%）, atrial premature beats 5 cases （9.3%）, atrial fibrillation 3 cases （5.6%）. Conclusion To improve the understanding of the characteristics of electrocardiogram in patients with hypertrophic cardiomyopathy, combined with echocardiography, which can greatly improve the accuracy of diagnosis of hypertrophic cardiomyopathy and reduce the misdiagnosis and missed diagnosis.
