Abstract

método e sistema de mapeamento de frentes de onda de ativação. a presente invenção refere-se a método e sistema de mapeamento cardíaco que inclui um dispositivo de exame médico para capturar dados ao longo do tempo em múltiplos locais de amostra sobre uma superfície de ao menos uma câmara de um coração, uma tela de exibição e circuitos de processamento configurados para processar os dados capturados para determinar uma descrição de uma propagação de frentes de onda de ativação associada a tempos de ativação sobre a superfície da ao menos uma câmara do coração, calcular traços da trajetória de propagação da frente de onda de ativação, em que cada traço descreve um ponto em uma frente de onda de ativação sendo propagado ao longo da superfície da ao menos uma câmara do coração de acordo com um avanço da frente de onda de ativação, de modo que os traços da trajetória de propagação da frente de onda de ativação descrevam a propagação de diferentes pontos de acordo com as frentes de onda de ativação correspondentes, preparar uma visualização mostrando a pluralidade de traços da trajetória de propagação da frente de onda de ativação em uma representação da ao menos uma câmara do coração e renderizar a visualização para a tela de exibição.
