Nearly four long minutes. That's how long Bob Quick's heart stopped beating in 2004 on a day he calls the best of his life. 'That heart attack changed everything for the better,' he said. His heart stopped. He didn't. In the years since that near-fatal episode, Quick has had stents implanted to support blood flow to his heart as well as an Abbott implantable cardioverter defibrillator (ICD) in his chest to help manage his heart disease and maintain a normal heartbeat.
