摘要
目的探讨心电图对扩张型心肌病诊断的价值及优势。方法回顾性收集2016年10月至2022年6月期间濮阳市安阳地区医院经临床已经确诊的扩张型心肌病(dilated cardiomyopathy,DCM)共152例。152例扩张型心肌病均经DR胸片、心电图以及超声心动图检查。选取了105例对照组(2018年8月至2022年6月期间住院的非扩张型心肌病患者)进行心电图结果对比。结果扩张型心肌病组的PtfV1(mm·s)数值为(0.029±0.008),左束支传导阻滞为20例(13.16%),QTc间期数值为(432.0±49.2),胸导联R波递减为39例(25.66%),QRS时限数值为(0.108±0.019),一度房室传导阻滞为13例(8.56%),对照组的PtfV1(mm·s)数值为(0.021±0.002),左束支传导阻滞为1例(0.95%),QTc间期数值为(386.8±26.6),胸导联R波递减为8例(7.62%),QRS时限数值为(0.088±0.016),一度房室传导阻滞为2例(1.90%),两组间差异均具有统计学意义(P<0.05)。结论心电图提示扩张型心肌病更易出现Ptfv1、左束支传导阻滞、QTc间期延长胸导联R波递减、QRS时限延长以及一度房室传导阻滞的改变,心电图在心律失常及心肌细胞的电活动方面具有不可比拟的诊断优势。
Objective To explore the value and advantage of electrocardiogram in the diagnosis of dilated cardiomyopathy.Methods A total of 152 cases of dilated cardiomyopathy(DCM)diagnosed in Anyang District Hospital of Henan Province from October 2016 to June 2022 were retrospectively collected.All152 cases of dilated cardiomyopathy were examined by DR Chest film,electrocardiogram and echocardiography.A control group of 105 patients(patients with non-dilated cardiomyopathy hospitalized between August 2018 and June 2022)were selected for ECG comparison.Results PtfV1(mm)in patients with dilated cardiomyopathy cardiomyopathy group,PtfV1(mm•s)value was(0.029±0.008),left bundle branch block was 20 cases(13.16%),QTc interval value was(432.0±49.2),and chest lead R-wave decline was 39 cases(25.66%).The QRS duration value is(0.108±0.019),the first degree atrioventricular block was 13 cases(8.56%),and the PtfV1(mm•s)value in the control group was(0.021±0.002),left bundle branch block in 1 case(0.95%),QTc interval value(386.8±26.6),chest lead R-wave decline in 8 cases(7.62%),QRS duration value(0.088±0.016).There were 2 cases of first degree atrioventricular block(1.90%),and the difference between the two groups was statistically significant(P<0.05).Conclusion The changes of Ptfv1,left bundle branch block,QTc interval prolongation,R-wave decline in chest leads,QRS duration prolongation,and first-degree atrioventricular block are more likely to occur in dilated cardiomyopathy.Ecg has an incomparable advantage in the diagnosis of arrhythmia and cardiomyocyte electrical activity.
