As noted by several others the pacemaker industry has indeed recognized the issues surrounding potential interference problems. Most probably remember the issues with microwave ovens - a problem solved over 30 years ago- but you still see the warning signs.
In general, the typical ham does not need to worry about their station causing interference with the pacemaker or implantable defibrillator. They are generally "hardened" to most forms of RF. When I was on the faculty at the University of Oklahoma we established a wireless (cell phones) EMC center and studied the impact on pacemakers: http://www.ou.edu/engineering/emc/Side/Achievments/Research%20Projects/Pacemaker%20Research/Pacemaker%20ResearchHome.dwt A general result was that analog modulation techniques (FM) did not impact the pacemakers. It was the digital modulation modes that caused some problems; all of which have been fixed for many years now. These studies were funded by both the pacemaker companies and the cell phone companies (manufacturers and service providers).
