Abstract

In a patient with chronic right bundle branch block who requires permanent pacing for the management of sinus node dysfunction, the impact of varying degrees of intentional fusion with a ventricular lead positioned in the right ventricular apex was evaluated with noninvasive Doppler echocardiography. Intentional fusion was shown to improve cardiac function.
