Abstract
BackgroundWolff-Parkinson-White (WPW) syndrome and idiopathic left ventricular tachycardia (ILVT) are rare and up to now the coexistence of both entities has rarely been reported.In patients with ventricular preexcitation the underlying mechanism of paroxysmal tachycardia most likely is atrioventricular reentrant tachycardia (AVRT). However, without ECG documentation of the tachycardia diagnosis of the underlying mechanism cannot be made due to similar clinical presentation of AVRT and ILVT.Case presentationWe report a case of a two-staged occurrence of two rare arrhythmias in a young adult, who was admitted to our hospital twice within 6 months because of paroxysmal tachycardia. WPW syndrome and ILVT as underlying arrhythmias have been diagnosed and were ablated successfully.ConclusionsThis case highlights the diagnostic defiance of rare tachycardia entities and the paramount importance of ECG documentation and analysis of all available tachycardia ECGs.

Paroxysmal tachycardias with regular heartbeat in the young without structural heart disease are most commonly caused by atrioventricular-nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT)
Summary
Wolff-Parkinson-White (WPW) syndrome and idiopathic left ventricular tachycardia (ILVT) are rare and up to now the coexistence of both entities has rarely been reported. Conclusions: This case highlights the diagnostic defiance of rare tachycardia entities and the paramount importance of ECG documentation and analysis of all available tachycardia ECGs. Background Paroxysmal tachycardias with regular heartbeat in the young without structural heart disease are most commonly caused by atrioventricular-nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT). Wolff-Parkinson-White (WPW) syndrome and idiopathic left ventricular tachycardia (ILVT) have a similar clinical presentation.
