A most important advance in the study of the electrical forces of the heart since the perfection of clinical electrocardiography is the development of spatial vectorcardiography. In conventional or scalar electrocardiography, each lead represents a projection of the electrical forces on a single axis, and a multiplicity of leads is used to obtain a detailed picture of the cardiac electrical forces. In spatial vectorcardiography, the electrical activity of the heart is represented as a single curve arrested in space; the electrocardiographic leads are considered as derivatives of this curve. Vectorcardiography, it is claimed, therefore offers a direct simple method of
