Abstract
We present a case of 8 year-old boy with several episodes of ventricular fibrillation in the course of tachycardia-mediated
cardiomyopathy and severe decompensated heart failure. The cardiomyopathy was caused by incessant long-RP tachycardia
that was resistant to pharmacotherapy. Despite initial suspition that the arrhythmia was permanent junctional reciprocating
tachycardia (PJRT) electrophysiology study revealed atypical atrioventricular nodal reentrant tachycardia. Due to clinical and
electrocardiographical presentation mimicking PJRT such arrhythmia merits the name ‘pseudo PJRT’.
