Junctional ectopic tachycardia in association with blunt abdominal trauma

Junctional ectopic tachycardia is recognized predominantly as a postoperative arrhythmia after surgery for congenital heart disease. Diagnosis and treatment distinguish it from more commonly observed mechanisms of supraventricular tachycardia. We present a case of junctional ectopic tachycardia that occurred in the setting of abdominal trauma caused by child abuse and then explore the significance of this arrhythmia in a patient with trauma.
