Description

The first implantable pacemaker made at St George's Hospital. In 1952, an American, Paul Zoll, had been the first to resuscitate a human heart using an electrical stimulus. At St George's, a team were treating patients with Stokes-Adams disease (heart block). Due to problems of infection during experiments using external pacemakers, Geoffrey Davies, a senior cardiac technician, designed an internal pacemaker. This became the main device in use at St George's for conditions where the control of the heart's rhythm was affected.
