Abstract

CIRCUITO ELECTRICO DESTINADO PARA AMPLIAR LA LONGITUD DE LOS IMPULSOS EN UN MARCAPASOS CARDIACO. COMPRENDE UNOS MEDIOS DE TEMPORIZACION QUE PROPORCIONAN UNA SEÑAL DE SALIDA DIGITAL; DICHA SEÑAL TIENE UN VALOR PROPORCIONAL AL TIEMPO TRANSCURRIDO POR UN IMPULSO ELECTRICO DE SALIDA; LOS CONDUCTORRES DE LA BASE (Q15 A Q20) ESTAN CONECTADOS A LAS RESPECTIVAS SALIDAS DE LAS SEIS FASES DE LOS MEDIOS DE TEMPORIZACION. CONSTA TAMBIEN DE UN CONVERTIDOR (20) DE DIGITAL A ANALOGICO QUE RECIBE LA SEÑAL DE LOS MEDIOS DE TEMPORIZACION Y QUE ESTA CONECTADO A UNA FUENTE DE ENERGIA (33) PARA PROPORCIONAR UNA SEÑAL DE SALIDA ANALOGICA; LA SEÑAL DE SALIDA AUMENTA CON EL TIEMPO EN UN RITMO INVERSAMENTE PROPORCIONAL A LA TENSION DE LA FUENTE DE ENERGIA. INCLUYE, ADEMAS, UN ELEMENTO COMPARADOR (26), CONECTADO PARA RECIBIR LA SEÑAL DE SALIDA ANALOGICA CUANDO LA CITADA SEÑAL ALCANZA UN NIVEL PREVIAMENTE DETERMINADO.
