Changes in Myocardial Perfusion During Chronic Multi Site Biventricular Versus Right Ventricular Apex Pacing in Patients With Normal Left Ventricular Function Undergoing His Bundle Ablation for Drug-refractory Atrial Fibrillation (SOS)

November 4, 2014 updated by: Vincent van Dijk, R&D Cardiologie
To determine whether Biventricular pacing in patients undergoing HIS bundle ablation for atrial fibrilation has beneficial effects on myocardial perfusion and left ventricularr ejection fraction.
