Which inventor is credited with developing the electrocardiograph?

The key idea is who created the first practical instrument to record the heart’s electrical activity. William Einthoven is the inventor credited for this breakthrough. He built the first workable electrocardiograph using a sensitive string galvanometer, enabling clear, clinical recordings of the heart’s electrical signals. His work in the early 1900s introduced the standard approach to recording ECGs, including the limb leads and the arrangement later known as Einthoven’s triangle, which made interpretation consistent across patients. This foundational device and method transformed how heart rhythms are studied and diagnosed, earning Einthoven the Nobel Prize in Physiology or Medicine in 1924. The other figures are known for different contributions—Helmholtz advanced electrical and physiological science but did not invent the ECG device; Garcia studied voice; Fleming discovered penicillin.
