A 41-year-old man was rushed to the ED by EMTs after fainting while relaxing with his family in the evening. In the ambulance they recorded ventricular fibrillation and shocked his heart with a defibrillator to correct the rhythm. He was still experiencing heart palpitations and reported he had noticed them on and off in recent weeks. He was very upset because his father died suddenly of a heart attack in his early 40s and the man was worried he too would have a heart attack. His ECG showed ST elevation with an upwardly convex descent to an inverted T wave in leads V1 and V2, and labs showed hyperkalemia.
