Predictability in complex atrial arrhythmias: The N/N –1 algorithm to guide ablation of atrial tachycardias

Macroreentrant atrial tachycardias (ATs) are some of the most challenging cases to accurately map and successfully ablate.1 Because patterns of scar and wavefront propagation are unique to each patient, the ablation procedure tends to be complex, time-consuming, and sometimes frustrating. Complex and detailed activation maps are painstakingly created, targets identified, and the tachycardia circuit successfully ablated. but frequently this results in the induction of a second, slower AT that requires repeating the entire process.
