The soccer player in this YouTube video has an implanted defibrillator. He apparently has a genetic condition that predisposes him to heart attacks, and when one occurs, the implanted defibrillator automatically goes into action, jolting the heart and effectively bringing him back to life. Scary, and inspiring the same time!
