Abstract

1/1 resumo “sistema e método para definir uma fonte rotativa associada com um distúrbio de ritmo biológico” um exemplo de sistema e método de definir uma fonte rotativa associada com um distúrbio de ritmo cardíaco é divulgado. uma pluralidade de localizações centrais de frentes de onda é calculada em uma pluralidade de pontos no tempo associados com o distúrbio de ritmo cardíaco. um trajeto rotativo que conecta a pluralidade de localizações centrais é então determinado. o sistema e método podem também determinar um núcleo provável associado com o trajeto rotativo. uma pluralidade de formas de difusão relativa associadas com a pluralidade das localizações centrais é calculada. uma pluralidade de pontos de intersecção de uma forma de difusão relativa mínima e outras formas de difusão relativa é determinada dentro do trajeto rotativo. um polígono delimitado dos pontos de intersecção é definido como o núcleo provável.
