| Outline of Final Research Achievements |
The ischemic heart disease such as the myocardial infarction would be lethal. In fact, the majority of those deaths would happen suddenly, resulting from the ischemia-induced cardiac arrhythmia. We studied the electrocardiographic findings, J wave, as a predictor for lethal arrhythmia. We showed the frequency of a J wave in general population. And we reviewed frequencies and morphologies of J wave in patients with and without ischemic ventricular fibrillation during induction of coronary spasm. As a result, we reported that the presense of J wave and the dynamic changes of J wave contributed to ischemic ventricular fibrillation, and that the J wave can be the predictive factor for occurrences of ischemic ventricular fibrillation. Also, we accumulated clinical features and genetic information of over 70 cases that had suffered from ischemic ventricular fibrillation, and presented analysis results including a treatment method for ischemia-induced arrhythmia at academic meetings.
