English

Subject field(s)
  • Cardiovascular System
DEF

An equilateral triangle used as a mathematical model of the standard electrocardiographic limb leads, in which the instantaneous heart vector in the frontal plane may be projected on the sides of the triangle thereby demonstrating that the algebraic sum of the potential differences as recorded in electrocardiographic leads I and III will equal that potential difference recorded in lead II.

  • Système cardio-vasculaire
CONT

Les dérivations bipolaires de Einthoven I, II, III sont constituées d'électrodes actives qui enregistrent la différence de potentiel entre les 2 points où elles sont appliquées : I = connexion bras gauche-bras droit, II = connexion bras droit-jambe gauche, III = connexion bras gauche-jambe gauche. Selon l'hypothèse de Einthoven, on admet arbitrairement que les lignes des dérivations I, II et III délimitent un triangle équilatéral frontal dont le centre correspond au centre de la masse cardiaque.
