Unusual Cause of a Cardiac Arrest in a Former African American Collegiate Athlete.

Yamaguchi-variant cardiomyopathy is an underreported but significant cause of cardiac arrest among athletes. We studied the hospital course of one patient who arrived at the emergency department after a sudden cardiac arrest while playing a recreational basketball game. We used the electronic medical record (Epic) to follow the notes, labs, imaging, and procedures that were performed. Although a rare disease, Yamaguchi syndrome should not be overlooked when working up a patient who has suffered a sudden cardiac arrest. Proper knowledge of automatic external defibrillators and basic cardiopulmonary resuscitation principles can have a significant positive impact, and the importance of these interventions should not be overlooked in patients with a sudden cardiac arrest.
