John Alexander Hopps, OC (May 21, 1919 – November 24, 1998) was a co-developer of both the first artificial pacemaker and the first combined pacemaker-defibrillator, and was the founder of the Canadian Medical and Biological Engineering Society (CMBES). He has been called the "Father of biomedical engineering in Canada." [1] [2] [3]
He then went on to discover he could use electricity to set the pace of a sick heart. In 1926, Lidwill was working at the Crown Street Women's Hospital in Sydney where he resuscitated a newborn baby with an electrical device. Lidwill's method was to put a needle into the heart to administer 16-volt impulses via the apparatus he had invented. [3]
Claude Schaeffer Beck (November 8, 1894 – October 14, 1971) was a pioneer cardiac surgeon, famous for innovating various cardiac surgery techniques, and performing the first defibrillation in 1947. [1] He was the first American professor of cardiovascular surgery, from 1952 through 1965. He was a nominee for the Nobel Prize in Medicine in 1952.
Each pulse causes the targeted chamber(s) to contract and pump blood, [3] 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 ...
Pacemakers are also sometimes used temporarily when someone is recovering from a heart attack or heart surgery, but in this case only the wires are inserted into the body; the pacemaker box stays ...
Sir Brian Gerald Barratt-Boyes KBE (born Brian Gerald Boyes, 13 January 1924 – 8 March 2006) was a pioneering New Zealand cardiothoracic surgeon.He was known for early development of cardiopulmonary bypass surgery, early implantation of a cardiac pacemaker before these devices became commercially available in 1961, early use of human cadaveric aortic homografts for aortic valve replacement ...
Kareem Abdul-Jabbar, 75, sits down with Prevention to share his atrial fibrillation diagnosis and experience. Atrial fibrillation, or AFib, is a common heart condition that causes irregular heartbeat.
The history of invasive and interventional cardiology is complex, with multiple groups working independently on similar technologies. Invasive and interventional cardiology is currently closely associated with cardiologists (physicians who treat the diseases of the heart), though the development and most of its early research and procedures were performed by diagnostic and interventional ...
