Two patients with inconclusive surface electrocardiogram patterns underwent nonfluoroscopy automatic mapping and remote‐controlled ablation of nonisthmus and isthmus‐dependent right atrial flutter.Methods and Results:A 0.08 magnetic vector force and a motor drive enable a complex steering of a new 8‐mm magnet tip electrode. The navigation system performs atrial electroanatomical mapping fully automatically. Total procedural fluoroscopy time for ablation of nonisthmus‐related atypical and isthmus‐dependent flutter was 8.5 and 3.2 minutes, respectively.Conclusion:Automatic electroanatomical mapping offers a promising option to effectively guide the remote‐controlled ablation of atrial reentry tachycardias and to reduce fluoroscopy time.
