[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 ...
Hi all, Willem Einthoven is credited with inventing String Galvanometer, but this is right way to say it: In 1895 Dutch Physiologist, Willem Einthoven, used a crude electrical sensing apparatus to establish that the beating heart produced four distinct signals, each one corresponding to a different ventricle.
Dutch physiologist Willem Einthoven developed the string galvanometer in the early 20th century, publishing the first registration of its use to record an electrocardiogram in a Festschrift book in 1902. The first human electrocardiogram was recorded in 1887, however only in 1901 was a quantifiable result obtained from the string galvanometer.
The account claimed to review the textual evidence available [2] from ancient sources on two disputed Bible passages: 1 John 5:7 and 1 Timothy 3:16. Newton describes this letter as "an account of what the reading has been in all ages, and what steps it has been changed, as far as I can hitherto determine by records", [ 3 ] and "a criticism ...
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 ...

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 . Whilst there he met his wife, [ 2 ] Alice Palmer, who was one of his students and daughter of George Palmer , MP for Reading and founder of the biscuit ...
