Einthoven's triangle transparency: A practical method to explain limb lead configuration following single lead misplacements

Abstract

Limb lead switches remain a significant source of electrocardiographic error that may lead to faulty diagnosis and improper clinical action. Methods to identify such errors have been the subject of many prior publications. A brief review of the mathematical derivation of the limb lead system is presented here, together with an additional method to help understand limb lead reversals using a transparency of the Einthoven's triangle. © 2010 MedReviews®, LLC.
