A bundle branch block refers to a defect of the heart`s electrical conduction system. ==Anatomy and physiology== The heart`s electrical activity begins in the sinoatrial node (the heart`s natural pacemaker), which is situated on the upper right atrium. The impulse travels next through the left and right atria and summates at the atrioventricula......

<cardiology, physiology> Abnormal conduction through one of the conductive branches which normally supply the right and left ventricles. ... Usually results in delayed conduction though either the right or left bundle branches where one ventricle is excited before the other because of absence of conduction in one of the branches of the bundle...

(BBB) a form of heart block involving delay or failure of conduction in one of the branches in the bundle of His, as determined by an electrocardiogram. It may be complete or incomplete; transient, intermittent, or permanent; and found in the right bundle branch, the left one, or both (bilateral). In complete bund...
