This Day in Science History - May 21 - EKG and EEG
May 21st was the birthday of two men who invented two
electric diagnostic devices that are often confused with each other. The
EEG, or electroencephalogram device, was invented by German
psychologist Hans Berger to record electrical signals from the brain.
The ECG or EKG, otherwise known as electrocardiogram was invented by
Dutch physician Willem Einthoven to measure the electrical current given
off by heart beats.
Perhaps nobody mixes these two devices up, but I sometimes do. All you have to remember: EEG - brain waves, ECG or EKG - heart beats.
