ablation at three arrhythmogenic pulmonary veins (PVs). Radiofrequency
(RF) applications eliminated all evidence of sharp PV electrical activity,
as shown in the corresponding elecrgrams before and after ablation from
the same sites. Note that the electrgrams of both left PVs are shown
during distal coronary sinus pacing (s= pacing stimulus), which separate
and highlights the PV potential (pvp). a= atrial optential; LIPV = left
