Football Injury Tonights NFL football game (Buffalo vs Cincinatti) was cancelled after a player collapsed after taking a direct helmet hit to the chest. He was transported to a Cincinatti hospital by ambulance and was listed in critical condition.
Two doctors that spoke on the situation referred to it as something called Commotio Codis.
This is a heart condition caused by blunt traumatic force to the heart by a powerful hit. Common to some degree in baseball or hockey where players are hit by a ball or a puck. Not as much in football.
Echocardiography is usually part of the emergency diagnosis examination. Ventripoint would probably be very useful for such a situation.
