[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 was born in Semarang on Java in the Dutch East Indies (now Indonesia), the son of Louise Marie Mathilde Caroline de Vogel and Jacob Einthoven. [2] His father, a doctor, died when Willem was a child. His mother returned to the Netherlands with her children in 1870 and settled in Utrecht.

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.
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 ]
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 ...
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.
