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.

Common Causes

Causes by Organ System

Cardiovascular Alcoholic cardiomyopathy, aortic insufficiency, aortic stenosis, aortic valve replacement, Chagas disease, coronary artery disease, dilated cardiomyopathy, endocarditis, exercise-induced LBBB, heart failure, hemochromatosis, hyperkalemia, hypertension, hypertensive cardiomyopathy, hypertrophic cardiomyopathy, hypertrophic obstructive cardiomyopathy (HOCM), ischemic cardiomyopathy, ischemic heart disease, left ventricular hypertrophy, left ventricular noncompaction (LVNC), left ventricular outflow tract surgery, Lenegre's disease, Lev's disease, lyme disease, myocardial infarction, myocardial ischemia, myocarditis, postpartum cardiomyopathy, restrictive cardiomyopathy, rheumatic fever with aortic valve involvement, sarcoidosis, septal myomectomy, TAVI, valvular heart disease
