AB Figure  6–1AThe  patient  had  electrophysiologic  assessment  for  WPW  and  recurrent  SVT.  AVRT  over  a  posteroseptal  AP  was  found  with  earliest  atrial  activation  during  tachycardia  at  the  proximal  coronary  sinus  (PCS)  electrode.  Ablation  adjacent  to  the  CS  os  was  performed  and  posteroseptal  preexcitation  was  abolished  with  no  inducible  tachycardia.  Fifteen  minutes  later,  SVT  was  again  induced  and  a  PVC  was  introduced  into  the  cycle  as  in  the  figure.  The  ablation  catheter  is  near  the  previous  site  and  the  coronary  sinus  catheter  has  not  moved.  Where  would  one  ablate  now?Graphic  Jump  LocationView  Full  Size||Download  Slide  (.ppt)
