Overview

Isolated left posterior fascicular block is often an uncommon finding owing to the fact that the left posterior fascicle has a dual blood supply, and it is exposed to lower pressures and turbulence, hence, it is rarely damaged. It usually accompanies right bundle branch block (RBBB) or in the setting of arteriosclerotic heart diseases such as myocardial infarction. Other less common causes include: infectious (e.g. diphteritic myocarditis, Chagas disease); genetic (e.g. myotonic dystrophy).

Causes

Life Threatening Causes

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