Figure 2: During catheter manipulation, tachycardia was easily inducible with the ventriculoatrial interval of 140 ms. During tachycardia, the retrograde conduction was eccentric, and the earliest A was seen in coronary sinus 5,6. Premature ventricular complex delivered on the His (fused premature ventricular complex) resulted in delay of the next A. This response is suggestive of retrogradely conducting decremental accessory pathway. However, during tachycardia, the local ventriculoatrial on coronary sinus 5,6 was very short which would argue against the decremental pathway
