[Permanent junctional reciprocating tachycardia causing cardiomyopathy in an adult woman].
A 35-year-old female was referred with progressive dyspnoea and elevated heart rate. Surface electrocardiography (ECG) showed supraventricular tachycardia (SVT) with long RP interval and inverse P waves. ECG revealed left ventricular dilation and severe systolic dysfunction. An electrophysiological (EP) examination was performed due to incessant SVT despite betablocker medication. Permanent junctional reciprocating tachycardia (PJRT) was diagnosed and successfully ablated. During follow-up, the patient's symptoms abated and ECG parameters normalized. PJRT is usually found in infants and children, but should also be considered as a rare cause of incessant SVT and tachycardiomyopathy in adults.
