Myocarditis

Myocarditis is a STEMI mimic that can cause nonspecific ST and T changes. It may also cause sinus tachycardia, AV blocks, ventricular arrhythmias, QRS and QT prolongation. There may also be signs of pericarditis.

What does this ECG with significant ST Elevation represent?

This ECG is from a man in his 30s who presented with a week of chest pain.

This ECG shows T wave inversion in V5-6 with J point notching and a short QT interval. Echo showed global hypokinesis and mild-mod systolic dysfunction. Troponin was elevated. Angiogram was normal. The diagnosis was myocarditis.

A 20-something male with acute chest pain

This ECG is from a man in his 20s who presented with sudden onset chest pain.

This ECG shows lateral ST elevation. Troponin was elevated. Echo showed a regional wall motion abnormality. Angiogram was normal. The cause was myocarditis.

A patient with chest pain and dynamic ST elevation

This ECG is from a woman in her 40s who presented with chest pain that had been waxing and waning over the past 24 hours. She had a history of renal failure on dialysis, hypertension, diabetes and a normal catheterisation a year ago. This was her initial ECG.

This ECG shows sinus tachycardia with nonspecific intraventricular delay, tall QRS and widespread PR segment depression. The ST segments are all discordant apart from V4 and V1. These changes were dynamic over serial ECGs. The cath was again normal. Echo showed a trace of pericardial effusion. The diagnosis was myopericarditis.
