Facts About the Pacemaker
- In 1926, Dr. Mark Lidwell, along with Edgar Booth, invented a portable device that could plug into a lighting point and the other half of the device could be plug into the corresponding cardiac chamber.
- Albert Hyman created his own version of the pacemaker in 1932. His device was powered by a spring-wound, hand-cranked motor.
- In 1950, John Hopps then built the first external pacemaker.
- In 1957, Earl Bakken created the first wearable external pacemaker.
- In 1958, the completely implantable pacemaker was inserted into an individual in Sweden. Unfortunately, the device was not successful and failed after three hours. The patient, Arne Larsson, received over twenty different pacemakers in his lifespan.
- In 1971, isotopes were replaced with lithium anode cells. The creation of a titanium metal encasement for the pacemaker was the final major breakthrough in the field.
An example of the pacemaker is a small device that is implanted in the chest that uses electrical impulses to regulate the heart beat.
