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.
