Summary

This study tested a newer pacing method (left bundle branch area pacing) against the standard method (right ventricular pacing) in 486 adults with atrioventricular block, a condition where the heart's electrical signals are delayed. The goal was to see if the newer method better preserves the heart's pumping ability and reduces risks of death, heart failure hospitalization, or need for advanced pacing therapy. Participants were followed over time to compare outcomes between the two pacing approaches.
