1. Commotio cordis

   Commotio cordis (Latin, "agitation or disruption of the heart") is a rare lethal disruption of heart rhythm that occurs as a result of a blow to the area directly over the heart (the precordial region) at a critical time during the cycle of a heartbeat. This leads to disrupting normal heart electrical activity, followed instantly by ventricular fibrillation, complete disorganization of the heart's pumping function, and cardiac arrest. It is not caused by mechanical damage to the heart muscle or surrounding organs and is not the result of heart disease. Its incidence in the United States is fewer than 20 cases per year, often occurring in boys participating in sports, most commonly in baseball when the hard ball strikes an unprotected chest. Commotio cordis occurs upon impact within a narrow window of about 40 milliseconds in the cardiac electrical cycle, explaining why it is so rare.If cardiopulmonary resuscitation (CPR) combined with use of an on-site automated external defibrillator is employed urgently, within three minutes of the impact, survival from commotio cordis can be as high as 58 percent.

1. Commotio cordis

   Commotio cordis is an often lethal disruption of heart rhythm that occurs as a result of a blow to the area directly over the heart, at a critical time during the cycle of a heart beat causing cardiac arrest. It is a form of ventricular fibrillation, not mechanical damage to the heart muscle or surrounding organs, and not the result of heart disease. The fatality rate is about 65%. It can sometimes, but not always, be reversed by defibrillation. Commotio cordis occurs mostly in boys and young men, usually during sports, most often baseball, often despite a chest protector. It is most often caused by a projectile, but can also be caused by the blow of an elbow or other body part. Being less developed, the thorax of an adolescent is likely more prone to this injury given the circumstances. The phenomenon was confirmed experimentally in the 1930s, with research in anaesthetized rabbits, cats and dogs.

1. Commotio Cordis

   A sudden CARDIAC ARRHYTHMIA (e.g., VENTRICULAR FIBRILLATION) caused by a blunt, non-penetrating impact to the precordial region of chest wall. Commotio cordis often results in sudden death without prompt cardiopulmonary defibrillation.
