Abstract

본 발명은 위상 특이점 판별 시스템 및 방법에 관한 것으로서, 심근 세포의 특정 지점에서 단일 전극 도자를 통해 측정한 단일 활동 전위도 신호(x[n], n은 자연수)를 수신하는 신호 수신부, 상기 신호 수신부가 수신한 단일 활동 전위도 신호로부터 위상(θ[n], n은 자연수)을 산출하는 위상 산출부 및 상기 위상 산출부가 산출한 위상을 통해 상기 심근 세포의 특정 지점이 위상 특이점인지 판별하는 위상 특이점 판별부를 포함하는 것을 특징으로 한다. 본 발명에 따르면 다전극 전극 도자가 아닌 단일 전극 전극 도자 사용을 통해 로터의 위상 특이점을 판별함으로써, 종래기술에 비해 소요되는 시간 및 소모되는 비용을 획기적으로 줄일 수 있으며, 로터의 위상 특이점을 정확하게 판별함으로써 심장 부정맥 치료를 위한 고주파 전극 도자 절제 시술에 활용할 수 있다는 효과가 있다.
