AF Regularization precedes AF Termination in a 34 year old man with continuous AF for 36 months, LA diameter 43 mm and LVEF 55 %. RAA CL prolongs after PVI and continues to do so to the point of AF termination. Intracardiac electrograms, CSp frequencies spectra and spatial activation vector appear to organize during ablation, which is quantitatively confirmed by the increase in the TRI and SRI. RAA=right atrial appendage; CSp=proximal coronary sinus; DF=dominant frequency; TRI=temporal regularity index; SRI=spatial regularity index.
