[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").
In 1904 he met Willem Einthoven at the International Physiological Congress in Brussels and then began to make use of a string galvanometer. He published on ECGs and vagus nerve stimulation experiments on frogs in 1908. [1] [2] He began to examine cardiac arrhythmias and their diagnosis. From 1903 to 1930 he worked at the department of zoology ...
Wasn't Clément Ader the inventor of the string galvanometer instead of Einthoven. [ edit ] According to Jaakko Malmivuo & Robert Plonsey: Bioelectromagnetism - Principles and Applications of Bioelectric and Biomagnetic Fields, Oxford University Press, New York, 1995. chapeter 15.1 Clément Ader was the inventor of the string galvanometer.
Graphical representation of Einthoven's triangle. Einthoven's triangle is an imaginary formation of three limb leads in a triangle used in the electrocardiography, formed by the two shoulders and the pubis. [1] The shape forms an inverted equilateral triangle with the heart at the center. It is named after Willem Einthoven, who theorized its ...
Different organisations are responsible for awarding the individual prizes; the Royal Swedish Academy of Sciences awards the Prizes in Physics, Chemistry, and Economics; the Swedish Academy awards the Prize in Literature; the Karolinska Institute awards the Prize in Physiology or Medicine; and the Norwegian Nobel Committee awards the Prize in Peace.

Helmholtz's polyphonic siren, Hunterian Museum, Glasgow. Hermann Ludwig Ferdinand von Helmholtz (/ ˈ h ɛ l m h oʊ l t s /; German: [ˈhɛʁ.man vɔn ˈhɛlmˌhɔlts]; 31 August 1821 – 8 September 1894; "von" since 1883) was a German physicist and physician who made significant contributions in several scientific fields, particularly hydrodynamic stability.

The E-meter is a simple psycho-galvanometer. It's got some increased sensitivity built into it and the myological reactions that you sometimes get in the galvanometer have been damped out by the circuitry, so that the mental reactions, the reactions of the spirit, on the body are emphasized and can be read more clearly. But that's simply the ...
