Abstract
This is the case of a 29-year-old female with sudden palpitations due to tachycardia. The atrial activation focusing point (AFP) was presumed to be the atrial entrance site within the reentry circuit of slow/fast atrioventricular nodal reentrant tachycardia by postpacing interval mapping. AFP is a novel ablation site because it is more distal to the His-bundle recording site and more atrial site compared to the conventional SP ablation site.
