Who is credited with the invention of the EKG?

Andreas Vesalius
Willem Einthoven
William Harvey
Edward Jenner

The correct answer is: Willem Einthoven

The invention of the EKG (electrocardiogram) is credited to Willem Einthoven, a Dutch physiologist. In the early 20th century, Einthoven developed the first practical electrocardiogram, establishing a method for recording the electrical activity of the heart. His work was groundbreaking in the field of cardiology and drastically improved the ability to diagnose heart conditions. Einthoven created the string galvanometer, which allowed for the precise measurement of heart electrical events. He is also known for his efforts in standardizing EKG leads, which helped in developing a consistent approach to cardiac monitoring and diagnosis. His contributions have had a lasting impact on medicine and continue to be fundamental in the evaluation of heart health, underscoring his significance in the history of cardiac care and technology. The other individuals listed made significant contributions to medicine, but in different fields. Andreas Vesalius is known for his work in human anatomy, William Harvey for his discovery of the circulation of blood, and Edward Jenner for developing the smallpox vaccine.
