Abstract

 Symptoms of blunt cardiac injury are often nonspecific, so electrocardiography (ECG) abnormalities may help in the diagnosis. We report a case of atrial fibrillation (AF) from cardiac injury in a traffic accident in which the patient recovered without pharmacotherapeutics. The patient was a 22-year-old man who was wearing a seatbelt when he sustained an injury by running into a truck. There were no subjective symptoms or physical findings on his chest upon admission to our hospital. His initial ECG showed AF without elevation of cardiac troponin I (cTnI) and no echocardiography abnormalities. However, cardiac troponin T (cTnT) was elevated 7 hours after the trauma. Two days later, he was discharged because of restoration of normal sinus rhythm and a normal cTnT level. This is a rare case because there are few reports of AF caused by cardiac injury that did not require drug therapy.
