Outline of Final Research Achievements

We investigated the electrocardiographic prognostic factors in cases with underlying heart disease. We tried to make a more accurate system construction by combining multiple factors and scoring. Especially, the fragmented QRS potential and symptoms were important in hypertrophic cardiomyopathy and Brugada syndrome, and could be applied to patients with ACHD. However, in ACHD cases, there was a large variety of diseases, and we found that it was difficult to predict using only conventional indicators. For scoring ACHD cases, it was found necessary to include quantification of invasive indicators.

Academic Significance and Societal Importance of the Research Achievements

心電図指標には様々なものがあるが、どの因子が予後を規定するかは不明である。今回の研究ではどの指標が重要で、何を注意して経過観察を行うべきかが明らかになった。特に基礎心疾患を有する症例について、心電図指標のみならず心室性期外収縮の形態によっても危険度を予測することが可能になった。これらの指標を注意深く観察することで若年者の突然死を予防することができれば社旗的意義は非常に高いといえる。
