The electromechanical and molecular consequences of various ventricular pacing modes have become a subject of intense interest in recent years due to profound clinical implications1–3. Compelling evidence indicates that right ventricular (RV) pacing can be detrimental to left ventricular (LV) function. The sequence of electrical activation during RV pacing may largely resemble the activation pattern of left bundle branch block (LBBB)4, and can result in dyssynchronous LV contraction5, 6. In accordance, RV pacing increases the risk for heart failure (HF) even in patients without pre-existing LV dysfunction.Cardiac resynchronization therapy (CRT) by means of biventricular (BiV) pacing was developed as a strategy to overcome the deleterious effects of electromechanical dyssynchrony in the failing heart and represents a major advance in HF therapy.
