The string galvanometer was one of the earliest instruments capable of detecting and recording the very small electrical currents produced by the human heart and provided the first practical Electrocardiogram (ECG). The original machines achieved "such amazing technical perfection that many modern day electrocardiographs do not attain equally reliable and undistorted recordings".
Famous quotes containing the word string:
“Amongst the learned the lawyers claim first place, the most self-satisfied class of people, as they roll their rock of Sisyphus and string together six hundred laws in the same breath, no matter whether relevant or not, piling up opinion on opinion and gloss on gloss to make their profession seem the most difficult of all. Anything which causes trouble has special merit in their eyes.”
—Desiderius Erasmus (c. 1466–1536)
