摘要：

Ablation of Atypical Atrial Flutter. Subeustachian isthmus-dependent typical atrial flutter has been well studied. We demonstrate a case with atypical atrial putter involving only the base of the right atrium around the inferior vena cava, Entrainment pacing and mapping studies documented a distinct circuit traversing the subeustachian isthmus, propagating through the posterobasal right atrium, and skirting the inferior vena cava, Successful radiofrequency ablation of the arrhythmia was accomplished by creating a linear lesion at the subeustachian isthmus, Mapping of the inferior vena cava region and the demonstration of concealed entrainment are essential steps in establishing the mechanism of the atypical atrial flutter.
