Abstract
It is unfortunate that although applications of the Mahalanobis-Taguchi system are starting to appear in various fields, their use could not be called widespread. One problem has been the lack of specific case study reports; another is the technical issues that make them difficult to apply. The medical field is one field in which wider application of the MT system is hoped for. The present study concerns the data preparation methods necessary for the interpretation of electrocardiograms. Diagnostic methods such as the recognition Taguchi (RT) method, the error root mean square method, and the transferability method have already been used, but here we propose the use of the both-sides T method. With this method, we found that it would be possible to proceed efficiently from diagnosis of disease through confirmation of treatment effect by use of a unified analytic formula. The data used were twelve-lead electrocardiogram images available on the Internet. After obtaining the consent of the image providers, we used the images by converting them to pixel counts.
