Abstract

Se describen un sistema y un método representativos para construir la información de la activación cardiaca. Se procesan una primera señal cardiaca y una segunda señal cardiaca mediante un dispositivo informático para determinar si existe un punto de cambio en una derivada de la primera señal cardiaca con respecto a una derivada de la segunda señal cardiaca por encima de un umbral. Se asigna un momento de inicio de la activación en la primera señal cardiaca en el punto de cambio para definir la activación cardiaca que indica un latido en la primera señal cardiaca si se determina que el punto de cambio está por encima del umbral.
