Evaluation of Cardioverter Capacity of Amiodarone Pre-electrical Cardioversion in Persistent Atrial Fibrillation

Phase: IV Population: Sample size= 122 patients; male and female; ≥ 18 y.o.; patients with persistent atrial fibrillation referred for electrical cardioversion; performed in Spain Number of Sites: 4 Study Duration: 15/10/2024 - 15/5/2026 Subject Participation Duration: 2-4 months (depending on the arm) Description of Agent or Intervention: amiodarone Objectives: Primary: To compare the efficacy of amiodarone in pre-ECV reversal to sinus rhythm in a one-month impregnation regimen versus a 5-day regimen Secondary: 1) Identify days from initiation of pre-ECV amiodarone to reversion to SR using a mobile device paired to the mobile phone; 2) To compare the joint efficacy in the reversion to SR pre-ECV and in the maintenance of SR at 1 month after ECV of a one-month pre-ECV amiodarone impregnation regimen vs a 5-day regimen Description of Study Design: Multicenter randomized open clinical trial. 122 Patients with persistent AF (≥7 days duration) electively referred for CVE will be included. Two amiodarone regimens administered pre-CVE will be compared evaluating their cardioverter efficacy. Patients will be randomized to 2 groups: 1. Treatment impregnation with amiodarone starting one month before ECV (600 mg/day 1st week, 400 mg/day 2nd week and 200 mg/day thereafter until ECV). 2. Treatment impregnation with amiodarone 800 mg/day started 5 days before ECV. Estimated Time to Complete Enrollment: 13 months
