The ECTOPIA trial is a randomized, multicenter, clinical trial to assess elimination of ventricular premature beats (VPB) with catheter ablation versus optimal anti-arrhythmic drugs (AAD) treatment with flecainide/verapamil or sotalol.


The ECTOPIA trial is a randomized, multicenter, clinical trial to assess elimination of VPB with catheter ablation versus optimal AAD treatment with flecainide/verapamil or sotalol. Due to the use of different AAD (with and without beta-blocking abilities) the investigators will be able to explore the secondary objectives. Finally, this study will assess safety of ablation of non-RVOT VPBs and long-term treatment with two different AAD.

Condition Premature ventricular contractions, ventricular extrasystoles
Treatment catheter ablation, Sotalol, Flecainide and verapamil
