Cardiac resynchronization therapy (CRT) has become an established therapy for patients with NYHA class 3 and 4 heart failure, with a left ventricular (LV) ejection fraction (EF) <35%, and a wide QRS complex of >120 ms, especially in patients with a complete left bundle branch block (CLBBB).1 A number of studies have shown that patients with these characteristics may benefit from this therapy in terms of quality-of-life (QoL), exercise capacity, LV function, LV dimensions/volumes, morbidity, and even mortality.1 The key to understanding these effects lies in the term asynchrony as the most important determinant for success of CRT. Asynchrony, which means that parts of the heart and particularly the LV are out of phase during LV contraction and relaxation, can occur at three levels within the
