A member asked:
What is bifascicular block and how is it treated?
5 doctors weighed in across 2 answers
see below: There are 3 fascicles or pathways for cardiac conduction in the heart: the right bundle branch, and the left bundle branch which is subdivided into anterior and posterior fascicles. When 2 of the 3 don't function, it is easily detected on ekg. This causes no symptoms and requires no treatment. Nonetheless it is abnormal and should prompt an evaluation of your general heart health.

Good question: Bifascicular block refers to conduction disturbances in which the right bundle branch and the left anterior fascicle or left posterior fascicle are blocked (fail to conduct an electrical impulse). It may occur in heart disease or in an otherwise normal heart. Progression to complete block is rare. Risk for death is low. Treatment not usually required. If symptomatic may need pacemaker.
