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.

摘要

肢体导联的改变仍然是心电图错误的一个重要来源，可能导致错误的诊断和不当的临床决策。识别这些错误的方法一直是许多先前出版物的主题。本文简要回顾了肢体导联系统的数学推导，并提供了一种使用爱恩托芬三角形透明胶片来帮助理解肢体导联反转的附加方法。
