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.

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.

+==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]], [[Ventricular septal defect surgery|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.
 ==Causes==
-* [[Pulmonary Embolism|Acute pulmonary embolism]]
+===Life Threatening Causes===
-* [[Atrial septal defect]]
+Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.
-* Blunt [[trauma]]
+*[[Citalopram|Citalopram toxicity]]
-* [[Ddx:Cardiomyopathy|Cardiomyopathy]]
+*[[Cocaine abuse]]
-* [[Cor Pulmonale]] - chronically increased right ventricular pressure and/or [[right ventricular hypertrophy]]
+*[[Heart failure]]
-* [[Coronary Heart Disease]]
+*[[Hyperkalemia]]
-* Familial
+*[[Myocardial infarction]]
-* [[Hypertension]]
+*[[Pulmonary embolism]]
-* [[Lenegre's Disease]]
-* [[Lev's Disease]]
-* Mechanical damage during right heart [[catheterization]]
-* [[Myocardial infarction]]
-* [[Myocarditis]]
-* [[Polymyositis]]
-* [[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.
-* Prenatal exposure to [[HIV]] type 1 may cause right anterior [[hemiblock]].
-* 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.
-===Transient RBBB===
+===Common Causes===
+*[[Cocaine abuse]]
+*[[COPD]]
+*[[Cor pulmonale]]
+*[[Coronary heart disease]]
+*[[Heart failure]]
+*[[Hyperkalemia]]

+*[[Myocarditis]]
