Article Snippet: In patients who presented in sinus rhythm, a standardized AF induction protocol was performed using right atrial decremental burst pacing with eight-beat sequences, starting with a 300-ms pacing cycle length and decreasing to 200 ms (or the effective atrial refractory period) by steps of 10 ms. A 3D electroanatomical map (CARTO mapping system, Biosense Webster) of the left atrium was obtained in AF using a 20-electrode circular mapping catheter (LASSO catheter, Biosense Webster).
