Figure 3: Negative adenosine test
After administration of iv Adenosine, AV block is seen (Shown as blocked P wave in figure). Ventricular pacing is started after this and shows no VA conduction confirming absence of accessory pathway conduction in both directions. CS d represent distal bipole of a decapolar catheter in coronary sinus. Rest of the catheter positions and abbreviations are same as in Figure 2.
Figure 4: Location of accessory pathway
Dots represent the number of cases that satisfied inclusion criteria, at each location. CS – Coronary sinus, MS-midseptal, LL-left lateral, LP – left posterior, LPS–left posteroseptal, RA – right anterior, RAS – right anteroseptal, RL – right lateral,RP – right posterior, RPS – right posteroseptal.
