mm has been described in normal subjects) Overall impression: In my opinion and experience, this ECG most likely represents a normal baseline ECG, but with a small chance of pericarditis instead. I texted this to Dr. Smith without any information, and this was his reply: "This could be pericarditis but probably is normal variant."

An Initial ECG was performed: Initial ECG: Sinus tachycardia with prolonged QT interval (QTc of 534 ms by Bazett). She was admitted to the ICU where subsequent ECGs were performed: ECG at 12 hours QTc prolongation, resolution of T wave alternans ECG at 24 hours Sinus tachycardia with normalized QTc interval. No ischemic ST changes.

The ECG shows sinus tachycardia, a narrow, low voltage QRS with alternating amplitudes, no peaked T waves, no QT prolongation, and some minimal ST elevation in II, III, and aVF (without significant reciprocal STD or T wave inversion in aVL). It is difficult to tell if there is collapse during diastole due to the patient’s tachycardia.
