Assessing Hemodynamic Impact and Management Strategy. This seemingly small deviation can point toward underlying structural heart disease, ischemic conditions, or simply be a benign finding in an otherwise healthy individual, making a thorough evaluation essential.
Presence of an rsR', R', or M pattern in lead V1 or V2. Because the left ventricle is activated later, the initial septal depolarization is reversed, eliminating the normal septal q waves and producing a characteristic QS or rS pattern in the right-sided leads.

Differentiating Left Bundle Branch Block Patterns Interpreting a left bundle branch block requires attention to opposite morphological changes. The left bundle branch further divides into the anterosuperior and posteroinferior fascicles, ensuring the left ventricle contracts almost simultaneously from endocardium to epicardium.
