Bundle branch block ecg findings represent a specific pattern of delayed electrical conduction within the ventricles, visible on the surface electrocardiogram. Identifying Right Bundle Branch Block ECG Criteria and Visual Characteristics Right bundle branch block is characterized by a distinct sequence of depolarization where the left ventricle activates normally, but the right ventricle is activated late via the intact septum.

The second positive deflection, or the 'R' prime, represents the delayed activation of the right ventricle, creating a classic 'rabbit ear' morphology that is often the first indicator clinicians identify. A disruption anywhere along this pathway, particularly within the fascicles of the left bundle branch, directly manifests as bundle branch block ecg patterns.
These branches ensure near-simultaneous depolarization of the ventricles, a process essential for efficient pumping mechanics. Isolated, asymptomatic findings in healthy individuals may be a normal variant.

A significant ST-T vector discordance, where the ST segment and T wave oppose the main QRS deflection, is a critical ancillary finding that supports the diagnosis. Management and Prognostic Implications.
