Male, 33-year-old patient (previously healthy) was admitted into the emergency room with oppressive chest pain. Hemodynamically stable.
Negative family history.
He did not use any medication or illegal drugs. No previous syncope. No fever during ECG recordings.
The physician interpreted the initial ECG as Supraventricular Tachycardia with aberrancy (SVT-A) and he administered adenosine injection, unsuccessfully.
Later, 50 J electrical cardioversion was conducted, which led to VF and a short while later 200 J defibrillation was applied, successfully.
Normal troponin and electrolyte levels.
The patient was moved to the Hospital, where coronary angiography was performed (normal). Normal echo.
