Einthoven's theory
WebThe cornerstones of this theory are the superposition and reciprocity theorems of Helmholz, upon which rest, respectively, the lead-vector concept of Burger and van Milaan and the lead-field concept of McFee and Johnston. The classical concepts of Einthoven and Wilson fit into this lead theory as a special case. 1.3 10.1.3 Bibliographic Notes WebFeb 2, 2024 · An EKG lead is a particular electrical “view” of the heart and is representative of flow of electricity toward and away from 2 points in the heart. The setup looks like this: Figure 1.4. 3: Image 3, Electric Flow. Each lead is named and will be labeled: RA, LA, RL, and LL. The easiest way to remember this is RA = right arm, LA = left arm ...

Einthoven recognized that these voltages were not independent, but that Lead I + Lead III = Lead II, a relationship known today as Einthoven’s law. From Einthoven to Burger
WebThe spatial organization of these leads forms a triangle in the chest (Einthoven's triangle) which is presented in Figure 18, panel B. According to Kirchhoff's law, the sum of all currents in a closed circuit must be zero. Since Einthoven's triangle can be viewed as a circuit, the same rule should apply to it.
