Commotio cordis （CC） is the acute death caused by the cardiac rhythm disorder after a sudden blunt external force to the precordium of a healthy person without previous heart disease. As one type of violent heart damage, CC is rare with relatively small external force and sudden death, therefore causing disputes. This paper reviews the epidemiology, mechanisms and the key points in forensic identification of CC, discusses the identification and antidiastole of CC, myocardial contusion, sudden cardiac death and death from inhibition, and provides assistance to forensic pathologists to identify such causes of death.
