RBBB, a pattern seen on the 12-lead ECG, results when normal electrical activity in the His-Purkinje system is interrupted for some reason. The normal sequence of activation is altered in RBBB, with a resultant characteristic appearance on the ECG manifest by a widened QRS complex and changes in the directional vectors of the R and S waves. This ECG pattern is often seen in clinical practice and generally regarded as benign. The anatomy, epidemiology, causes, symptoms, ECG findings and diagnosis, differential diagnosis in ECG, treatment, complications, prognosis, with respect to RBBB are outlined here, demonstrating some typical ECGs of RBBB.
RBBB 是 12 导联心电图上的一种模式，是由于希氏-浦肯野系统的正常电活动由于某种原因而中断所致。在 RBBB 中，激活的正常顺序被改变，心电图上表现出宽 QRS 复合物和 R 波和 S 波的方向向量的变化。这种心电图模式在临床实践中经常见到，通常被认为是良性的。这里概述了 RBBB 的解剖学、流行病学、病因、症状、心电图表现和诊断、心电图鉴别诊断、治疗、并发症、预后，并展示了一些 RBBB 的典型心电图。
