Einthoven's theory
WebEinthoven's law: [ īnt´ho-venz ] if electrocardiograms are taken simultaneously with the three limb leads , at any given instant the potential in lead II is equal to the sum of the potentials in leads I and III. WebEinthoven also conceived the famous equilateral triangle with leads I, II, and III at its sides and the calculation of the electrical axis (in the frontal plane) depicted as a single vector with an arrow at the center of the triangle. Einthoven recognized the great potential importance of the ECG as a diagnostic and investigative tool and his ...
