His-bundle Pacing vs. Right Ventricular Apical Pacing in Patients With Reduced Ejection Fraction

"A standard pacing electrode (Medtronic 4076) will be placed in RV apex (or RV septum as a secondary option) and in the right atrial appendage (if indicated).~A dedicated His-bundle pacemaker electrode (Medtronic 3830) will be placed in the region of His bundle, using a dedicated introducer sheath (Medtronic C304 or Medtronic C315). His-bundle potentials will be identified and His-bundle capture (non-selective or selective) will be ascertained using an electrophysiology recording system. Device programming will focus on providing physiological atrioventricular delay and safety RV pacing as backup."
