The Strength of a New Signal

Published:October 26, 2021DOI:
      Whereas Augustus Waller first recorded an “electrogram” from the intact skin’s surface in 1887, Willem Einthoven received the 1924 Nobel Prize in Medicine and Physiology for decoding intracardiac transmembrane anion transients into a clinically useful output in 1903.

      Willem Einthoven: the father of electrocardiography.
      Einthoven’s Triangle for electrocardiogram (ECG) limb lead placement, designed to detect the electronic fields generated by a biological neural network during cyclical myocardial activity, is still used to amplify electrical potential changes between leads as dynamic vectors. An enduring apprenticeship of cardiology training remains 12-lead ECG interpretation, a skill that continues to be a significant component of clinical practice and cardiovascular medicine specialty board examinations.
