Abstract
We describe of a unique pattern of cardiac dyssynchrony in a patient with a biventricular physiology and systemic right ventricle (RV): the interventricular dyssynchrony due to a contraction delay between the left ventricle and RV. In the present case, the cineangiography and intracardiac electrocardiography of the RV did not reveal intraventricular dyssynchrony of the RV, but revealed interventricular dyssynchrony. In addition, the pressure curves of the ventricles exhibited time phase differences between the two ventricles. The cardiac resynchronization therapy determining the pacing lead positions based on the idea of interventricular dyssynchrony induced reverse cardiac remodeling in this patient with systemic RV dysfunction.
