Study Summary
This is a randomized, prospective clinical trial to determine the effects of two different pacemaker atrioventricular delay (AV delay) settings on heart function in patients with dual chamber pacemakers implanted for symptomatic bradycardia with long PR intervals (delayed conduction between upper and lower chambers of the heart). The study will compare a long, fixed AV delay (standard) with an optimized AV delay for each individual using echocardiography (experimental).
Primary Outcome
Comparison (∆) of change in echocardiographic parameters left ventricular (LV) dimension at end-diastole, left ventricular (LV) dimension at end-systole, and tricuspid annular plane systolic excursion (cm) from baseline to followup, in Optimized AV delay versus Long-fixed AV delay groups. A reduction LV dimension indicates improvement in function, and an increase in tricuspid annular plane excursion represents an improvement in function.
