[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 ...
A tree-topper or treetopper is a decorative ornament placed on the top (or "crown") of a Christmas tree or Chrismon tree. [1] [2] Tree-toppers come in many forms, with the most common being a star (representing the Star of Bethlehem) or an angel (representing the Angel Gabriel), both from the Nativity.

He invented the first practical electrocardiograph (ECG or EKG) in 1895 [ 1 ] and received the Nobel Prize in Physiology or Medicine in 1924 for it ("for the discovery of the mechanism of the electrocardiogram").
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 ...
