The pacemaker changed the world for medical reasons. Before, the 1st pacemaker would be portable and would have to be plugged into an outlet. This changed the population of people that have bradycardia. The pacemaker improved as the years went on. Later on it was implantable and had batteries. Today, the pacemaker also can be charged from the outside without getting surgery to replace the battery due to the new technology that we have today.
