Sometimes it doesn't work right, because of some kind of blockage or other problem that causes the heart to beat too slowly. In these cases, cardiologists — or heart doctors — will often surgically implant an electronic pacemaker as a replacement. Pacemaker research began in 1899, but it wasn't until 1958 that the first patients received these lifesaving devices.
