A heretofore unre‐ported unusual mechanism in the initiation of the paroxysmal supraventricular tachycardia fPSVTj in a patient with WPW (Wo/ff‐Parkinson‐Whitej syndrome was observed using His bundJe recordings. The patient initially had some degree of AV conduction disturbance at the JeveJ of the AV node. A premature atriaJ impulse initially activated the ventricle exclusively through the accessory pathway and the same impulse re‐excited the ventricle via the AV nodai‐His axis after finishing the pure pre‐excitation with marked prolongation of the AH and the HV intervals. After finishing this double ventricular response it traversed to the atrium to produce the PSVT.
