Background
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.
In patients with ventricular preexcitation the underlying mechanism of paroxysmal tachycardia most likely is atrioventricular reentrant tachycardia (AVRT). However, with...

Context 1
... Physical exam was unremarkable, the patient did not take any medication. Similar episodes with palpitations over several minutes and one syncope in the past were re- ported. Initial 12-lead ECG showed a shortened PR inter- val with prominent delta waves in I, II, aVL, V 4 -V 6 and R/ S transition at V 4 /V 5 suggesting a right midseptal pathway (Fig. 1). Diagnosis of WPW syndrome was established. Non-invasive cardiologic work-up did not show significant ...

Background:
The ST segment is component of the QRS-T complex located between the QRS and the T wave. ST segment changes during tachycardia with narrow QRS mainly takes the form of ST segment depression. This phenomenon is often observed in young healthy people for whom an ischemic background is unlikely.
Materials and methods:
The study included...
