Anatomy and Physiology of the Bundle Branch System The heart's rhythmic efficiency relies on a precise electrical conduction system that coordinates the contraction of the atria and ventricles. Patients may be entirely asymptomatic, with the condition discovered incidentally during a routine physical examination.

The bundle branches, specifically the left and right, are the final pathways in this system before the electrical impulse reaches the ventricular muscle. 9 Heart failure, unspecified Often secondary to LBBB Prognostic Implications and Management Strategies.
In contrast, the chronic form typically develops gradually, often as a consequence of structural heart disease such as hypertension, aortic valve stenosis, or cardiomyopathy. Clinical Manifestations and Diagnostic Criteria Identifying a chronic left bundle branch block relies heavily on the interpretation of an electrocardiogram (ECG), where the characteristic wide QRS complex exceeding 120 milliseconds and specific patterns in leads V5, V6, I, and aVL are key indicators.
