Abstract

Un marcapasos cardíaco numérico mejorado para suministrar impulsos de estímulo a los electrodos de entrega, adaptado para conectarse con un corazón, caracterizado por: una fuente de impulsos de reloj, un contador de intervalo para contar los impulsos de reloj, un generador de impulsos de estímulo accionado por la salida del contador de intervalo, un detector para producir una salida amplificada de señales indicativas de los latidos del corazón; y un contador de intervalo de control para contar un número preseleccionado de impulsos de reloj que corresponden a un intervalo refractario preseleccionado.
