Description:

Arne Larsson receives the first fully implanted pacemaker in a secret emergency operation. This pacemaker was developed by Dr Rune Elmqvist. Because of lack of time, he coated the components of the first device with epoxy resin in a plastic cup. Two electrodes connected to the pacemaker provided to energy to stimulate the heart. The first device had to be replaced after just a few hours, however Arne Larsson lived a further 43 years with a total of 26 pacemakers. This showed that pacemakers could be implanted within humans, and paved the way for commercially available pacemakers.
