title: Physical and chemical injury as causes of sudden cardiac death: the forensic forum.
abstract: Physical and chemical injuries account for the largest number of sudden, unexpected cardiac deaths in persons between the ages of 1 and 44 years. Blunt-force injuries, lacerations, avulsions, and contusions of the heart and great vessels sustained during motor vehicle crashes constitute the most prevalent type of lethal physical trauma to the cardiovascular system. The second most prevalent type of trauma is from penetrating and perforating wounds inflicted by firearms. The mechanisms of these injuries are discussed, with emphasis placed on those factors contributing to lethality. The three most prevalent chemicals associated with sudden cardiac death-ethyl alcohol, cocaine, and tricylic antidepressants-are briefly mentioned.
