[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 (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").

The Bellevue Spruce tree comes in three heights — 6.5, 7.5, and 9 feet — and it has a slim profile that isn’t as wide at the base, making it ideal for smaller living spaces.
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.

It need not snow Dec. 25 to fit the weather service's definition of a white Christmas: There just needs to be at least 1 inch of snow on the ground. A trace amount of snow does not count.
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.
