A bundle branch block is a defect of the bundle branches or fascicles in the electrical conduction system of the heart.
In left bundle branch block (LBBB) the conduction in the left bundle is slow. This results in delayed depolarization of the left ventricle, especially the left lateral wall. The electrical activity in the left lateral wall is unopposed by the usual right ventricular electrical activity. The last activity on the ECG thus goes to the left or away from V1. Once you remember this, LBBB is easy to understand. Diagnosis of myocardial infarction in LBBB can be difficult. Other definitions. The above definition of left bundle branch block is rather broad.
