Abstract
The outline of the Nagoya Program, the most representative software package for computerized
electrocardiography in Japan, is described. First, the history and current status
of research and its transfer to commercial products for computerized interpretation
of electrocardiograms is briefly reviewed. Second, development and testing of the
Nagoya Program is depicted, referring to a gold standard for evaluation and the database
being used for this purpose, and to its participation in the CSE study. Third, a description
of signal acquisition and wave identification is given, followed by the detection
of rhythm disturbances. Next, algorithms for contour classification, which consist
of decision-tree logic established through trial and error and making use of the database
of ECGs, are described. Finally, special features and future plans of the Nagoya Program
are mentioned.
