Right bundle-branch block
Right bundle-branch block
by Alike Medical Team ∙ Updated on June 13, 2023
General
Right bundle-branch block (RBBB) is an electrical heart problem, causing arrhythmias, which are irregular heart beats. The sinoatrial node is the heart’s pacemaker, which passes the electrical signs from the ventricles to the atrias. The signal goes down through two bundle branches at the same time, causing both ventricles to contract at the same time. When there is a right bundle branch block, the signal goes down the right branch slower than the left branch, causing the ventricles not to contract at the same time. This condition creates irregular heartbeat. RBBB may be caused due to myocarditis, chest trauma, myocardial infarction, right heart catheterization, changes in branch structure.
