Einthoven (Willem Einthoven)

Willem Einthoven was a Dutch scientist who invented the electrocardiogram (ECG or EKG) in the early 20th century. This device records the electrical signals produced by the heart as it beats. By analyzing these signals, doctors can assess the heart's rhythm, detect abnormalities, and diagnose conditions like arrhythmias or heart attacks. Einthoven’s work, particularly the creation of standard leads and the concept of the electrocardiogram, revolutionized cardiac care by providing a non-invasive way to monitor heart health accurately and quickly.
