This report discusses the employment of the electrical characteristics of biologically active points (BAP) in the meridian of the heart to solve the task of prognosticating recurrence of myocardial infarctions during the rehabilitation period using fuzzy decision rules. Employment of only the electrical characteristics of informative BAP was found to provide a reliability level of greater than 0.85 in decision-making, with a significant uncertainty zone. If additional features characterizing long-term psychoemotional tension − lipid peroxidation and antioxidant activity − are included, the reliability of prognoses of recurrence of myocardial infarction during remission reaches 0.95. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.
