Willem Einthoven

Definition

Willem Einthoven was a Dutch physiologist who is credited with the invention of the electrocardiogram (ECG or EKG), a diagnostic tool that records the electrical activity of the heart. His contributions were instrumental in understanding the electrical properties of cardiac muscle and its role in the heart's function.
