The benefit of a dual chamber pacemaker and the atrial and ventricular synchronization in patients with two ventricles is widely accepted. The purpose of this study was to choose the optimal AV interval in patients with congenital heart disease after definitive palliation of univentricular hearts. Therefore, different AV intervals were programmed and hemodynamic aspects were examined by Doppler echocardiography. The interval found was different from normal heart morphology and two ventricular hemodynamics. (PACE 2003; 26:2048–2049)
