An Accurate, Clinically Practical System For Spatial Vectorcardiography

This paper describes a news improved system of spatial vectorcardiography that is practical for clinical use. It represents an optimum compromise among such factors as soundness of theoretic basis, accuracy, reproducibility, signal-to-noise ratio, and speed of application. Some of its advantages over currently employed systems include a rational physical basis, corrections for torso shape, avoidance of left arm, insensitivity to individual variability of ventricle location, and accuracy comparable to applicability of 3-dimensional torso-model data to the human subject. Detailed description of electrode placement, practical procedures, and useful technics is included.
