Clinical trial
A Prospective, Multi-Center, Randomized, Open Label Trial to Determine if a Common Atrial Fibrillation Risk Locus Modulates Differential Response to Antiarrhythmic Drugs
Name
2018-1299
Description
In this pilot and feasibility study, the investigators will enroll patients with frequent symptomatic episodes of atrial fibrillation (AF) in a cross-over study testing two different classes of anti arrhythmic drugs (AADs). This pilot and feasibility study will provide preliminary data for a larger study in which the investigators will test the hypothesis that a common AF genetic risk allele modulates response to different AADs.
