Abstract

Dual atrioventricular node (AV) pathway physiology or the presence of so-called slow conduction pathway is according to various studies demonstrable in up to 35% of normal people during electrophysiology study (EPS). In only a small number of them, it has a clinical significance.
We present a case of a patient with a very rare electrophysiological manifestation of active slow pathway, double ventricular response to one atrial complex. The problem was successfully treated with radiofrequency ablation.
This form of conduction via AV node is probably much more common than it was previously described in the literature, but unfortunately it is rarely recognized and is generally refractory to medical therapy.

Keywords
