Key result
The application of Einthoven's equilateral triangle method allows for a detailed analysis of the normal and pathologic spread of the excitation wave in the human heart.
Introduces and revises the application of Einthoven's equilateral triangle method for analyzing the spread of excitation waves in the human ventricle.
May aid ECG vector analysis of ventricular activation; leaves open prospective validation in contemporary practice.
We are now in the possession of a method and sufficient anatomic and physiologic information for a detailed and fairly accurate analysis of the normal and pathologic spread of the excitation wave in the human heart. Such an analysis will help to clarify some of our somewhat hazy and even inaccurate ideas asto the causes of the form of the normal and pathologic electrocardiogram. Using the method of the equilateral triangle devised by Einthoven,¹I attempted an analysis of the propagation of the wave of electronegativity in the human heart in 1914.²This paper has for its purpose the more extended introduction of the method among American clinicians and a revision of some of the ideas developed in that paper. The work of Rothschild and Lewis³on the velocity of conduction in the heart muscle has been especially helpful in revising our ideas as to the propagation of the electronegative
