目的探讨右位心样心电图改变的临床意义。方法对35例常规心电图检查呈右位心样改变的患者心电图结合影像学及临床分析。结果 35例心电图中P波极性正常12例,P波极性异常23例;V1～V6导联主波方向均向下、R/S逐渐变小。跟踪超声心动图等影像检查发现心脏位于右侧胸腔的右位心26例;心脏位于中线上的中位心5例;心脏位于左侧胸腔的左位心4例。结论心电图呈右位心样改变是心脏异位的主要表现,除了右位心,左位心、中位心伴心房反位、房室连接顺序不一致也可以有类似的心电图表现,并且往往伴有复杂的先天性心脏病。
Objective To investigate the clinical significance of right-sided cardiac electrocardiogram (ECG) changes. Methods Electrocardiogram (ECG) combined imaging and clinical analysis of 35 patients with right heart-like changes in conventional electrocardiogram were performed. Results The electrocardiogram showed that the P wave was normal in 12 cases and the P wave was abnormal in 23 cases. The main waves in V1 ~ V6 lead were downward and R / S was gradually decreased. Tracking echocardiography and other imaging examination found that the heart is located in the right side of the right chest 26 cases of the right heart; the center of the heart in the midline in 5 cases; the left heart in the left chest in 4 cases. Conclusion Electrocardiogram showed right heart-like changes are the main manifestations of ectopic heart, in addition to right centroid, left centroid, median with atrial anti-bit, atrioventricular connection sequence inconsistency can also have similar ECG manifestations, and often accompanied by Complex congenital heart disease.
