Key Facts

  1. In 1929, Australian physician Mark Lidwill and physicist Edgar Booth developed one of the earliest artificial pacemakers, an external device used to stimulate the heart.
  2. In 1950, Canadian engineer John Hopps created a practical portable external pacemaker, helping advance cardiac pacing technology.
  3. The first successful implantable pacemaker was developed in 1958 by Swedish physician Åke Senning and engineer Rune Elmqvist and implanted in patient Arne Larsson.
  4. Early pacemakers had limited battery life, but the invention of the implantable lithium-iodine battery in the late 1960s greatly improved reliability and longevity.
  5. Modern pacemakers can sense the heart’s rhythm, adjust pacing automatically, and often be implanted through minimally invasive procedures.
