Testing a heart pacemaker feature for heart failure patients

This trial is testing a pacemaker system called SyncAV, which includes a special feature that automatically adjusts the timing between your heart's upper and lower chambers. The study focuses on people who have heart failure and a specific type of electrical delay in their heartbeat called left bundle branch block or similar conduction delays. Researchers want to see whether this automatic timing adjustment helps improve how well the pacemaker works for you.

Heart failure patients often have electrical problems that make their heart chambers beat out of sync, which weakens the heart's pumping power. This new automatic timing feature is designed to help coordinate those beats more effectively, and doctors want to confirm it actually works well in real patients.
