'Stereovectorcardiogram' made by stereolithography.
A method for making directly a single solid vectorcardiogram is reported. A solid vectorcardiogram was made by employing an apparatus for production of three-dimensional objects by stereolithography. Stereolithography is a computer-aided manufacturing technique that is practiced in conjunction with computer-aided design and engineering. To design the solid vectorcardiogram, voltages in the X, Y and Z axes obtained according to the Frank lead are memorized in the computer-aided design system. By use of the stereolithography apparatus, the designed solid vectorcardiogram is formed in a vat filled with liquid plastic. In the vat, the plastic changes rapidly from liquid to solid in the presence of ultraviolet light so that a solid vectorcardiogram made of solid plastic may be formed.
