| Outline of Final Research Achievements |
In this study, we clarify the mechanism of generating alternans in mathematical cardiac models. Two systems are considered: (1) the system of making sustainable periodic oscillations and (2) the system of the ventricular muscle with ideal inputs. As a result, we obtain that the alternans occurs through abnormalities of the conductivity and the reversal potentials of the potassium ion, and it triggers cardiac death.
