Left Bundle Branch Versus Minimized Ventricular Pacing in Patients With Sick Sinus Syndrome and Prolonged AV Interval

The goal of this clinical trial is to compare two pacemaker strategies: Left Bundle Branch Area Pacing (LBBAP) and Minimized Ventricular Pacing (MVP) in patients requiring a permanent pacemaker for sick sinus syndrome and prolonged AV interval. It will also evaluate the safety and feasibility of the LBBAP method in these patients. The main questions it aims to answer is: \*Is LBBAP with physiological AV interval better than Minimized Ventricular Pacing? Researchers will compare the LBBAP group (aiming for conduction system capture with physiological AV intervals) to the MVP group (aiming to minimize ventricular pacing with prolonged AV intervals) to evaluate the optimal pacing strategy. Participants will: * Be randomly assigned to either the LBBAP group or the MVP group. * Undergo a pacemaker implantation procedure according to the specific criteria for their assigned group. * Visit the clinic for regular checkups to measure pacing function and ensure the device settings remain compliant with the study protocol.
