Wilhelm Einthoven

Willem Einthoven was a Dutch doctor and scientist who invented the electrocardiogram (ECG or EKG) in the early 20th century. This device records the electrical activity of the heart, providing essential information about heart health and function. Einthoven’s work allowed doctors to diagnose heart problems more accurately and non-invasively. He was awarded the Nobel Prize in Physiology or Medicine in 1924 for his contributions. His innovations fundamentally advanced cardiovascular medicine, making it possible to monitor the heart’s activity in real time and improving patient care worldwide.
