摘　　要：目的分析十二导联心电图对扩张型心肌病的诊断价值。方法选取在医院进行治疗的扩张型心肌病患者74例,所有患者均行十二导联心电图检测,对R波递增不良、左胸联高电压、QRS低电压、异常Q波、ST-T改变、传导阻滞、心律失常情况进行分析。结果 74例扩张型心肌病患者中心律失常发生率为45.95%;R波递增不良发生率为67.57%;R_(V6)/R_(V5)>1发生率为62.16%,R_(V6)≥3.5 mV或R_(V5)+S_(V1)≥3.5发生率为36.49%,R_(V6)/R_(max)≥3发生率为31.08%,连续三个心搏的S波和R波电压之和QRS总电压V_6>V_5发生率为36.49%;QRS低电压发生率13.51%;异常Q波发生率为21.62%;传导阻滞发生率为41.89%。结论十二导联心电图可反映扩张型心肌病患者常出现的多种异常表现,提高诊断水平。Objective To analyse the diagnosis value of 12-lead electrocardiogram in dilated cardiomyopathy. Methods Selected 74 cases patients with dilated cardiomyopathy in the hospital. All patients were detected by 12-lead electrocardiogram. Poor R wave progression,left chest high voltage,QRS low voltage,abnormal Q wave,ST-T change,conduction block and arrhythmia were analysed. Results The incidence of arrhythmia in 74 patients with dilated cardiomyopathy was 45. 95%. The incidence of R wave increase was 67. 57%. The incidence of RV6/RV5 1 was 62. 16%,The incidence of RV6≥3. 5 mV or RV5＋ SV1≥3. 5 was 36. 49%,The incidence of RV6/Rmax≥3 was 31. 08%,The sum of the S wave and the R wave voltage of the three consecutive fuities QRS total voltage V6 V5 was 36. 49%,QRS low voltage incidence 13. 51%; The incidence of abnormal Q wave was 21. 62%. The incidence of conduction block was 41. 89%. Conclusion 12-lead electrocardiogram can reflect the abnormal appearance of dilated cardiomyopathy and improve the diagnostic value.
