Abstract

A 32-year-old man with a 20-year history of palpitation showed a short PQ interval and delta wave on 12-lead ECG. An electrophysiological study showed that the atrio-His (AH) and His-ventricular intervals were not influenced by rapid right atrial pacing or by bolus injection of adenosine triphosphate (ATP). The AH interval was shortened by coronary sinus ostium (CSos) pacing. Ventricular stimulus to the atrial activation interval was not affected by ATP but shortened by para-Hisian pacing and orthodromic His bundle activation was followed by atrial activation. The tricuspid - inferior vena cava isthmus was blocked by CSos pacing, but Ith conduction existed during low lateral right atrial pacing. (Circ J 2003; 67: 715 - 717)
