Atrial Tachycardia

The purpose of this prospective, randomized, double-blinded study is to further evaluate the safety and efficacy of varying doses of intravenous magnesium in the treatment of AFF RVR.

Demonstrate the safety and effectiveness of the Ablacath™ Mapping Catheter and Ablamap® System in patients with all types of atrial fibrillation (AF) including paroxysmal or persistent or long-standing persistent, undergoing and De Novo or Redo procedures.
Phenotype patients and demonstrate the prognostication power of Electrographic Flow (EGF®) maps among all subjects using 12-month follow-up outcomes following EGF-guided mapping and ablation.

Atrial tachycardia is a symptomatic arrhythmia, for which an effective treatment is a catheter ablation procedure. The goal of the Ripple AT-Plus study is to evaluate two methods of performing catheter ablation for atrial tachycardia. The main outcome assessed during the study is long-term recurrence of atrial tachycardia following the catheter ablation procedure.
