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.
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 ...

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.
