[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.
From 1906, he corresponded with the Dutch physiologist Willem Einthoven concerning the latter's invention of the string galvanometer and electrocardiography, and Lewis pioneered its use in clinical settings. Accordingly, Lewis is considered the "father of clinical cardiac electrophysiology".
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 ...

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.
However, Einthoven needed an exact way of measuring the minute amounts of current. In 1897 a French electrical engineer, Clement Ader, invented the "string galvanometer", containing a tensioned string of quartz. In 1903, Einthoven modified Ader's machine, adding electrodes attached to the patients limbs and thorax.
