A middle-aged (44) man with sudden onset chest pain.

ECG of a middle-aged man with chest pain.

Question: What is the ECG diagnosis?

[Updated 29 August 2015]

The ECG showed widespread ST elevation and – perhaps more specifically – widespread PR segment depression. This is consistent with acute pericarditis. The aetiology cannot be determined from the stem as no further information was given. However, this man had symptoms of upper respiratory tract infection and conjunctivitis a few days before the onset of chest pain, and was finally postulated to have adenovirus pericarditis.
