Abstract

resumo método para reconstruir informações de ativação cardíaca, sistema para reconstruir informações de ativação cardíaca, e, método para tratar de um distúrbio de ritmo cardíaco trata-se de um sistema e método exemplificativos para reconstrução de informações de ativação cardíaca. um sinal de análise e um sinal de referência são processados para determinar se há um primeiro ponto de mudança em uma primeira derivada da ordem selecionada do sinal de análise em relação a uma primeira derivada da ordem selecionada do sinal de referência acima de um primeiro limiar. o sinal de análise e o sinal de referência são processados para determinar se há um segundo ponto de mudança em uma segunda derivada da ordem selecionada do sinal cardíaco de análise acima de um segundo limiar. um tempo de início de ativação é atribuído ao sinal cardíaco de análise em um ponto com base em uma associação matemática do primeiro ponto de mudança e do segundo ponto de mudança para definir ativação cardíaca que indica um batimento no sinal cardíaco de análise. 1/1abstract method for reconstructing cardiac activation information, system for reconstructing cardiac activation information, and method for treating a cardiac rhythm disorder is an exemplary system and method for reconstructing cardiac activation information. An analysis signal and a reference signal are processed to determine if there is a first shift point in a first derivative of the selected order of the analysis signal relative to a first derivative of the selected order of the reference signal above a first threshold. the analysis signal and the reference signal are processed to determine if there is a second shift point in a second derivative of the selected order of the cardiac analysis signal above a second threshold. An activation start time is assigned to the analysis heart signal at one point based on a mathematical association of the first shift point and the second shift point to define cardiac activation that indicates a beat at the analysis heart signal. 1/1
