Einthoven’s galvanometer used a skinny silver-plated quartz fiber to measure electrical indicators. When the fiber carries current, placing it in a magnetic field causes it to be displaced because of the pressure of the magnetic field on the present, in keeping with "Einthoven’s String Galvanometer," a 2008 paper in the Texas Heart Institute Journal. The fiber’s motion was magnified and projected on a running movie sheet, which recorded the sign. The device measured the electrical signals extra exactly, more accurately, and quicker than Waller’s machine, because of the motion of the quartz fiber. In 1905 Einthoven partnered with the Leiden University Medical Center to conduct clinical trials. At around 272 kilograms, the machine was too heavy to be transported from Einthoven’s laboratory to the medical center. Instead, hospitalized patients were linked to the string galvanometer using a telephone wire that ran from the hospital to the laboratory, a distance of about 1.5 kilometers.
