Institutions. University of Leiden. Willem Einthoven (21 May 1860 – 29 September 1927) was a Dutch medical doctor and physiologist. He invented the first practical electrocardiograph (ECG or EKG) in 1895 and received the Nobel Prize in Physiology or Medicine in 1924 for it ("for the discovery of the mechanism of the electrocardiogram").

Augustus Desiré Waller FRS (12 July 1856 – 11 March 1922) was a British physiologist and the son of Augustus Volney Waller. He was born in Paris, France. He studied medicine at Aberdeen University, where he qualified in 1878 and obtained his M.D. in 1881. [1] In 1883, he became a lecturer in physiology at the London School of Medicine for Women.
biophysicist. Norman Jefferis "Jeff" Holter (February 1, 1914 – July 21, 1983) was an American biophysicist who invented the Holter monitor, a portable device for continuously monitoring the electrical activity of the heart for 24 hours or more. Holter donated the rights to his invention to medicine. [1][2][3]
Holter monitor. Cardiac monitoring generally refers to continuous or intermittent monitoring of heart activity to assess a patient's condition relative to their cardiac rhythm. Cardiac monitoring is usually carried out using electrocardiography, which is a noninvasive process that records the heart's electrical activity and displays it in an ...
Rune Elmqvist (1 December 1906 – 15 December 1996) was a Swedish physician turned engineer who developed the first implantable pacemaker in 1958, working under the direction of Åke Senning, senior physician and cardiac surgeon at the Karolinska University Hospital in Solna, Sweden. Elmqvist was born in Lund, and received his MD in 1939.
From 1906, he corresponded with the Dutch physiologist Willem Einthoven concerning the latter's invention of the string galvanometer and electrocardiography, and Lewis pioneered its use in clinical settings. Accordingly, Lewis is considered the "father of clinical cardiac electrophysiology".
November 19, 1890. Died. September 11, 1952. Alma mater. University of Michigan. Known for. Cardiology. Frank Norman Wilson (19 November 1890 – 11 September 1952) was an American cardiologist known primarily for his contributions to electrocardiography. [1][2][3][4]
