Nuclear-powered pacemaker. Display model of a nuclear-powered heart pacemaker developed by the US Atomic Energy Commission in the 1970s. A pacemaker supplies electrical impulses along wires connected to the heart. These electrical impulses help to keep the heart beating regularly when a patient has an irregular heartbeat (cardiac arrhythmia). The first modern pacemakers were developed in the 1950s and 1960s. They initially used short-lived mercury batteries. In the late 1960s,atomic batteries using radioisotopes were developed,but this was soon superseded by the development of lithium batteries in the early 1970s. Photographed circa 1973 | |
