The first implantable pacemaker (reproduction)

Implantable artificial pacemakers generate electrical impulses which stimulate the heart muscle by means of electrodes to cause the heart to beat. In October 1958, Arne Larsson, a patient in Sweden, became the first person in the world to receive a pacemaker implant. The device consisted of two transistors, a capacity, and a rechargeable battery embedded in an epoxy resin.
