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").
[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.
In 1901 to 1905, Einthoven developed the string galvanometer, which could measure and record the heart's electrical activity. Electrodes were place on three points, the “Einthoven leads”, the right and left arms and on the left foot same as today and provided precise recordings of the heart. [9] This led to Einthoven's Nobel Prize in 1924.
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.
In 1901, Einthoven, working in Leiden, the Netherlands, used the string galvanometer: the first practical ECG. [93] This device was much more sensitive than the capillary electrometer Waller used. In 1924, Einthoven was awarded the Nobel Prize in Medicine for his pioneering work in developing the ECG.

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.
