[4] Einthoven developed a sensitive form of string galvanomter that allowed photographic recording of the impulses associated with the heartbeat. He was a leader in applying the string galvanometer to physiology and medicine, leading to today's electrocardiography. [5] Einthoven was awarded the 1924 Nobel prize in Physiology or Medicine for his ...
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").
MLA Style Manual, formerly titled MLA Style Manual and Guide to Scholarly Publishing in its second (1998) and third edition (2008), was an academic style guide by the United States–based Modern Language Association of America (MLA) first published in 1985. MLA announced in April 2015 that the publication would be discontinued: the third ...
[4] [5] In 1944, a 32-page guide appeared as an article in the same journal. [3] [6] The first edition of the APA Publication Manual was published in 1952 as a 61-page supplement to the Psychological Bulletin, [7] [8] marking the beginning of a recognized "APA style". [3] The initial edition went through two revisions: one in 1957, and one in ...

The electrocardiograph was impractical to use until Willem Einthoven, a Dutch physiologist, innovated the use of the string galvanometer for cardiac signal amplification. [2] Significant improvements in amplifier technologies led to the usage of smaller electrodes that were more easily attached to body parts. [ 1 ]
1887 – Willem Einthoven invents electrocardiography (ECG/EKG) [100] [101] 1890 – Emil von Behring discovers antitoxins and uses them to develop tetanus and diphtheria vaccines. 1895 – Wilhelm Conrad Röntgen discovers medical use of X-rays in medical imaging
However, Einthoven needed an exact way of measuring the minute amounts of current. In 1897 a French electrical engineer, Clement Ader, invented the "string galvanometer", containing a tensioned string of quartz. In 1903, Einthoven modified Ader's machine, adding electrodes attached to the patients limbs and thorax.
