Which scientist developed the electrocardiograph in 1903?

William Einthoven is the scientist who developed the electrocardiograph in 1903. He built a sensitive instrument called the string galvanometer that could convert the heart’s tiny electrical signals into visible tracings. In 1903 he produced the first recognizable electrocardiograms using three limb leads arranged around the body, forming Einthoven’s triangle. This setup established a practical and reproducible way to record cardiac electrical activity, laying the groundwork for modern ECG interpretation. Einthoven’s pioneering work earned him the Nobel Prize later on. The other names mentioned contributed to related electrical or physiological advances, but they did not create the ECG in 1903.
