==Overview==
Left bundle branch block is a cardiac conduction seen on the [[electrocardiogram]] ([[ECG]]) whereby there is an impairment of transmission of the cardiac electrical impulse along the fibers of the left main bundle branch, or both the left anterior fascicle and the left posterior fascicle.  Most causes of [[LBBB]] are the result of some form of cardiac disease but LBBB is also known to be associated with non cardiac causes.

Overview

Left bundle branch block is a cardiac conduction seen on the electrocardiogram (ECG) whereby there is an impairment of transmission of the cardiac electrical impulse along the fibers of the left main bundle branch, or both the left anterior fascicle and the left posterior fascicle. Most causes of LBBB are the result of some form of cardiac disease but LBBB is also known to be associated with non cardiac causes.

Causes

Life Threatening Causes

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