Cardiac pacemaker, Birmingham, England, 1960-1970
Before implantable pacemakers were developed that contained batteries, attempts were made to power them from outside the chest. This induction-type cardiac pacemaker has a power unit and two induction coils. The battery and the coil are carried by the patient. It was made by Joseph Lucas of Birmingham, an engineering company with Queen Elizabeth Hospital. The rate of electrical output was increased or decreased using a simple adjustable switch. One million people worldwide are now fitted with pacemakers.
