Sudden cardiac arrest due to blunt anterior chest wall impact (Commotio Cordis) usually occurs in young athletes who are struck by a baseball or other projectile in the precordium. Survival is extremely rare if the induced ventricular fibrillation (VF) is not defibrillated immediately at the scene. We report here a rare case of a one-year-old infant survivor of cardiac arrest caused by blunt chest impact during an accidental fall from a fourth story window. Eye witnesses reported to have seen him land on the front of his chest directly onto the plastic rain cover on the ground floor. He was transferred to a nearby hospital within minutes, where ventricular fibrillation was recorded. Immediate cardiopulmonary resuscitation and defibrillation and was successful. He recovered without any subsequent sequelae. To the best of our knowledge, this rare incident represents the first time that an infant has survived such cardiac arrest in these circumstances that has been recorded in the literature. This has implications for the management of paediatric fall injuries.
