Case presentation

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.

  4. What is diagnostic ECG-4 performed 24 hours after admission?
  5. What is the diagnosis ECG-5 performed 72 hours after being asymptomatic admission with high right precordial V1H V2H
