Geoffrey Wickham
Geoffrey Gordon Wickham (28 October 1933 – 23 April 2024) was one of the pioneers of artificial pacemaker, cardiac pacemaking. Geoffrey was born in 1933 in Camperdown, Victoria, Camperdown, Victoria, Australia to dairy farmer parents. In 1963 he co-founded the medical instruments company Telectronics Pty Ltd in Sydney, Australia, Sydney, and served as the company's Chief Engineer from 1963 to 1970 and Technical Director from 1963 to 1978. He was elected an Honorary Life Governor of Royal Prince Alfred Hospital, Sydney in 1982, and was appointed Officer of the Order of Australia in June 2000 "for service to the design of medical equipment, particularly in the development of the implantable cardiac pacemaker". Wickham had no formal engineering training, finishing High School at Year 8 to commence work as a radio and electrical repairman. At age 21 he passed the Year 12 examinations by night study at the South Australian School of Mines and Industries, while working as a technicia ...

Artificial Pacemaker
A pacemaker, also known as an artificial cardiac pacemaker, is an Implant (medicine), implanted medical device that generates Pulse (signal processing), electrical pulses delivered by electrodes to one or more of the Heart chamber, chambers of the heart. Each pulse causes the targeted chamber(s) to muscle contraction, contract and pump blood, thus regulating the function of the electrical conduction system of the heart. The primary purpose of a pacemaker is to maintain an even heart rate, either because the heart's natural cardiac pacemaker provides an inadequate or irregular heartbeat, or because there is a heart block, block in the heart's electrical conduction system. Modern pacemakers are externally programmable and allow a cardiologist to select the optimal pacing modes for individual patients. Most pacemakers are on demand, in which the stimulation of the heart is based on the dynamic demand of the circulatory system. Others send out a fixed rate of impulses. A specific ...
