PARENTS, COACHES, and PLAYERS you need to pay attention and learn something new as this could save a life one day!

Commotio cordis (Latin, “agitation of the heart”), also sometimes referred to as a concussion of the heart, occurs when a player sustains a blow to the area directly over the heart (chest region) at a critical time during the cycle of a heart beat causing cardiac arrest. It is a form of ventricular fibrillation (V-Fib), not mechanical damage to the heart muscle or surrounding organs, and not the result of heart disease, so this can happen to anybody! Most of the casualties of this trauma are young with an average age of less than 16 years old and a fatality rate that is high; 65 out of 100 dying.

A player may collapse, either suddenly or shortly after the event, and become unresponsive and lose pulses. According to the US Commotio Cordis Registry, the most common sports involved are youth baseball, softball and ice hockey, and has been reported in la cross and soccer. In each case, chest blows have been caused by a projectile such as the baseball, hockey puck, etc… In sports where there is not a solid hard ball or object, Commotio cordis resulted from elbow, shoulder or helmet contact in the chest area around the heart.

While Commotio cordis may, in some cases be prevented, the risk cannot be eliminated entirely. According to the American Heart Association Journals, “Chest protectors are another potential means to prevent Commotio cordis; however, their benefit has not yet been shown.”

The rate of successful recovery continues to be relatively low, but is slowly improving due to increased awareness and sideline responsiveness of coaches, athletic trainers and parents. It is important to respond immediately with the “CAB” – Compression, Airway and Breathing along with defibrillation and calling emergency responders. Effective response may save a young player’s life!

Although not a common emergency on the field, sudden cardiac death can and does occur and there is considerable underestimation of its true incidence. Having access to defibrillators at sporting events as well as having knowledgeable athletic trainers are keys to improving the survival rates for those who have suffered sudden cardiac arrest. Additionally, it is important to educate the public, players, coaches and the athletic community on the importance of preventing blows to the portion of the body over the heart and lower chest.
