Cardiac Concussion
Little League Baseball Sudden Death A 16yo player was struck in the chest by the baseball thrown from home plate as he attempted to steal third base. Shortly after standing he collapsed with seizure like activity and stopped breathing.
Little League Baseball Sudden Death The coach initiated CPR and local EMS documented arrival of an ACLS team 8 minutes after receiving the call from the field. Attempts to resuscitate were unsuccessful.
