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.

ST Elevation after Stab Wound to the Heart

This ECG is from a young man presented after a stab wound to the chest. Rapid ED diagnosis of cardiac penetrating trauma was made by ED ultrasound, and the patient went to the OR and had a wound to the right atrium repaired.  There was no laceration of any coronary vessel.  He did well.  This ECG was recorded at day 3 because of tachycardia.
