[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 ...

Einthoven also described the electrocardiographic features of a number of cardiovascular disorders. In 1897, the string galvanometer was invented by the French engineer Clément Ader. [92] In 1901, Einthoven, working in Leiden, the Netherlands, used the string galvanometer: the first practical ECG. [93]
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 ...
Joseph John O'Connell (1861–1959), U.S. – number of inventions relating to telephony and electrical engineering; Theophil Wilgodt Odhner (1845–1903), Sweden/Russia – the Odhner Arithmometer, a mechanical calculator; Paul Offit (born 1951), U.S., along with Fred Clark and Stanley Plotkin, invented a pentavalent Rotavirus vaccine
Williams traveled to Holland to study the methods of Willem Einthoven in 1911. [ 2 ] He constructed the first string galvanometer in America, pioneered vectorcardiography , discovered the ventricular vulnerable period, and first determined the 60-Hz current required to produce ventricular fibrillation with body-surface electrodes.
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.
