この研究室は、不整脈の診断と治療を中心に、電気生理学的手法と最新の画像・遺伝子解析を組み合わせた研究を展開しています。主な研究対象は心房細動や心室不整脈などの致命的な不整脈で、これらの疾患がどのようなメカニズムで発生・維持されるのか、そして患者ごとにどのような治療が最適なのかを明らかにすることを目指しています。研究手法としては、カテーテルアブレーション（カテーテルを用いた焼灼治療）の実施過程で得られる心臓の電気信号を記録・解析する方法が中心です。これに加えて、磁気共鳴画像検査による心臓組織の可視化、遺伝子解析、人工知能を活用した深層学習による画像解析など、多角的なアプローチを採用しています。さらに、植込み型除細動器などの医療デバイス関連の臨床課題も研究対象としており、感染症の原因微生物の同定やデバイス機能の長期経過観察も行われています。得られた知見としては、不整脈の基盤となる心臓組織の異常部位の同定、治療後の再発予測因子の解明、遺伝子異常と複数の心疾患の関連性などが報告されています。これらの研究を通じて、より正確な診断と効果的で安全な治療方法の開発に貢献することを目指しています。
