Figure 2. Induction of SVC-AF
AF was induced by 170 ms of rapid electrical stimuli from the portion of
the shortest SVC-ERP (ABL 1-2). The red asterisks indicate the
initiation of SVC-AF from the SVC potential. The Pentaray catheter was
within the SVC, and SVC potentials were recorded.
Abbreviations: ABL, ablation site; AF, atrial fibrillation; CS, coronary
sinus; ERP, effective refractory period; HRA, high right atrium; RVa,
right ventricular apex; SVC, superior vena cava.
