Left bundle branch block-induced cardiomyopathy: a distinctive form of cardiomyopathy that might require a dedicated form of treatment.

The His-Purkinje system is the ventricular component of the cardiac conduction system that orchestrates the electrical impulse propagation which underlies every contraction of the heart. It originates from the AV-node and runs down to the interventricular septum and subdivides into the left and right bundle branches. These major branches divide further and spread diffusely along the sub endocardium. [1],[2] Damage in one of those branches may result in impaired electrical conduction.
