Frist EKG (ECG) Machine


In this first EKG Machine, Right and Left hands and Left legs were immersed in jars of salt solution as electrodes !

Willem Einthoven (The Netherlands), used the string galvanometer to describe various deflections as features of a number of cardiovascular disorders. He was awarded the 1924 Nobel Prize for Physiology or Medicine for his discovery.
