Biatrial atrial tachycardia (BiAT) is a rare form of atypical macro-reentrant AT (MRAT) that can be difficult to characterize and ablate. Ablation of regions demonstrating spatiotemporal dispersion (SD) has shown a high rate of atrial fibrillation (AF) termination to either sinus or MRAT during ablation.

BackgroundIn medical practice, atrial fibrillation (AF) is intricately associated with heart failure (HF). The primary composite endpoint was defined as recurrence of atrial tachycardia over 30 s. AF patients received 4-step ablation composed of EIVOM, pulmonary vein isolation (PVI) and linear ablation. vs. 93.9%).
