High-definition mapping of permanent junctional reciprocating tachycardia: Deeper insights into atrial activation and branching

Year: 2026

Type: article

Abstract: Permanent junctional reciprocating tachycardia (PJRT), originally described by Coumel et al in 1967,1 is a very rare type of supraventricular tachycardia (1%), mostly seen in children and infants.2 PJRT involves an atypical accessory pathway (AP) with long and decremental unidirectional retrograde conduction,3 even if some more exceptional cases of anterograde conduction with overt preexcitation have been reported.4,5
