AV Delay Optimization vs. Intrinsic Conduction in Pacemaker Patients With Long PR Intervals
Sorry, in progress, not accepting new patients
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).

Effectiveness Study of Circumferential vs. Segmental Ablation in Paroxysmal Atrial Fibrillation
Sorry, in progress, not accepting new patients
This is a PI-initiated study that aims to evaluate the efficacy of two different methods of paroxysmal atrial fibrillation (PAF) ablation. There are currently two strategies for PAF ablation that are routinely performed by electrophysiology clinicians: (1) circumferential pulmonary vein ablation (CPVA) and (2) segmental pulmonary vein isolation (SPVI). However, it is not known if one approach is better than the other. This randomized study will evaluate and compare the efficacy of CPVA versus SPVI in subjects undergoing ablation for paroxysmal atrial fibrillation only. Subjects will have a 50/50 chance of receiving either the CPVA or SPVI ablation method.
