The Image Tetrahedron in Man Determined by Reciprocal Stimulation of a Tridimensional Esophageal Electrode
The anatomic apices of a tetrahedron were located on the image surface of living man by reciprocal stimulation of an electrode placed in the esophagus at the assumed electric center of the heart. The rectilinear components of the three-dimensional electrode were not oriented with respect to the axes of the body. Therefore, it was possible to determine the shape of the image tetrahedron but not its orientation in the body. The method is applicable to living man with the electrode placed at any assumed electric center of the heart.
