Overview

Right bundle branch block can result from various causes which include: cardiovascular (e.g. Atrial septal defect, cardiomyopathy, coronary artery disease, Ebstein anomaly); iatrogenic (e.g. Cardiac catheterization, cardiac transplantation, post cardiac surgery); infectious (e.g. Chagas disease, HIV, infective endocarditis, Lyme disease); pulmonary (e.g. COPD, cor pulmonale , pulmonary embolism, pulmonary hypertension), and many other disease conditions.

+*[[Heart failure]]
-* Septal reduction therapy with ethanol ablation in patients with [[hypertrophic cardiomyopathy]] and left ventricular outflow tract obstruction
+*[[HIV]]
-* Surgery for correction of [[congenital heart disease]] is the most common cause of RBBB among children in the United States. This includes surgery for repair of an isolated VSD or another [[congenital heart disease]] that includes a [[VSD]] (eg, double-chambered right ventricle, AV canal defect, or [[tetralogy of Fallot]]). The incidence of RBBB varies and ranges from 25-81% after repair of a VSD to 60-100% after repair of tetralogy of Fallot.  The risk of RBBB after surgery varies depending upon the proximity of the VSD to the [[His-Purkinje system]].
+*[[Hyperkalemia]]
-* [[Valvular heart disease]]
+*[[Hypertension]]
+*[[Infective endocarditis]]
-===Transient RBBB===
+*[[Left ventricular noncompaction]]
-* [[Hyperkalemia]] - causes depression of the His-Purkinje conducting system
+*[[Kearns-Sayre Syndrome]]
-* Mechanical damage during right heart [[catheterization]] - observed in 5% of the patients. Resolves when the catheter is removed.  Associated [[LBBB]] can cause [[complete heart block]] in such situations leading to [[cardiac arrest]].  A temporary pacemaker is inserted during the procedure in patients with LBBB to prevent sudden cardiac arrest.
+*[[Lev's disease]]
-* Occasionally following thrombolytic therapy in patients with [[myocardial infarction]] and new RBBB
+*[[Lyme disease]]
-* [[Pulmonary embolism]]
+{{col-break|width=33%}}
-* [[Premature atrial contraction]]s or [[supraventricular tachycardia]] may cause a transient form of right bundle branch block. This occurs when a premature impulse is conducted from the AV node to the His bundle while the right bundle branch remains in its refractory period, but the left bundle is not. As a result, conduction down the right bundle branch is delayed or blocked.
