Atrial Fibrilation Termination Endpoint

Brief summary

Recent data has demonstrated that focal sources are determinant in human atrial fibrillation (AF) perpetuation. The investigators sought to identify crucial areas for AF perpetuation during our routine electrogram (EGM)-based substrate ablation.

Atria fibrillation termination during procedure240 minconversion to atrial tachycardia (AT) or sinus rhythm

Secondary

MeasureTime frameDescription
Crucial points240 minCrucial points were defined by areas where ablation immediately extended the cycle length\> 20% of AF CL, or regularized Atrial Fibrilation (AF) into Atrial Tachycardia (AT) or converted AF (or AT) into Sinus Rythm
