com·mo·ti·o cor·dis

(kō-mō'shē-ō kōr'dis)
A disturbance in the electrical activity of the heart induced by blunt trauma to the anterior chest (as in athletic injuries, steering wheel injuries, and criminal assaults) without demonstrable structural damage. It can lead to ventricular fibrillation or other fatal arrhythmias and is among the more frequent causes of sudden death in athletes.
