Coumel's sign reversed: What is the mechanism?

A patient presented with documented narrow QRS tachycardia. During electrophysiological study, he has orthodromic reciprocating tachycardia with atrial activation consistent with left free wall accessory pathway. With induction of tachycardia, beats with LBBB morphology have shorter cycle length tha...

description A patient presented with documented narrow QRS tachycardia. During electrophysiological study, he has orthodromic reciprocating tachycardia with atrial activation consistent with left free wall accessory pathway. With induction of tachycardia, beats with LBBB morphology have shorter cycle length than those with narrow QRS. What is the mechanism?
