Permanent junctional reciprocatig tachycardia (PJRT) and dilated cardiomyopathy

Abstract Permanent reciprocating junctional tachycardia (PJRT) is re-entrant atrial tachycardia caused by an accessory pathway. It is mainly diagnosed in the neonatal period or in early childhood, although sometimes it is not diagnosed until the adult age. Clinical signs of this tachycardia include variable rate 130-200/bpm, P waves negative in inferior leads, PR interval shorter than RP interval, it finishes in the presence of AV-block and starts again spontaneously with acceleration of the sinus frequency. It is refractory to conservative treatment, so catheter ablation of accessory pathway is the therapy of choice. The all characteristics of this tachycardia as well as the refractory to conservative therapy were found in the case of 14-year-old girl who also had dilatative cardiomyopathy. The question of cause and consequence appeared: whether the arrhythmia is a consequence of dilatative cardiomyopathy, or it is tachycardia- induced cardiomyopathy
