Abstract

SE DESCRIBE UN NUEVO MARCAPASOS DE VELOCIDAD DE RESPUESTA QUE UTILIZA TIEMPO DE CONTRACCION ISOVOLUMICO (IVCT) COMO UNA RESPUESTA DE SEÑAL DE CONTROL A LAS DEMANDAS METABOLICAS. ESTA SEÑAL DE CONTROL SE INYECTA EN EL CIRCUITO DE TEMPORIZACION DE UN MARCAPASOS DE VELOCIDAD ADAPTABLE ESTANDAR PARA MEJORAR LA CAPACIDAD DE RESPUESTA DEL MARCAPASOS EN RELACION DIRECTA CON EL CAMBIO DE LAS NECESIDADES METABOLICAS DEL PACIENTE MIENTRAS REALIZA SUS ACTIVIDADES DIARIAS. SE DESCRIBE UNA CONFIGURACION TIPICA QUE UTILIZA IVCT DERECHO O IZQUIERDO DEL CORAZON PARA EL CONTROL DE VELOCIDAD, EN LA QUE LA VELOCIDAD DE PASO SE DETERMINA POR LA DURACION DEL IVCT. DADO QUE LA VELOCIDAD DE PASO Y DEL IVCT ESTAN LINEALMENTE RELACIONADAS, SE PUEDE UTILIZAR UN FACTOR DE CONVERSION SENCILLO PARA TRANSFORMAR LA DURACION DEL IVCT EN LA DURACION DEL INTERVALO DE ESCAPE DEL MARCAPASOS (VELOCIDAD DE PASO). AUNQUE EL IVCT DEL CORAZON DERECHO E IZQUIERDO PODRIAN SER UTILIZADOS PARA EL CONTROL DE VELOCIDAD, POR MOTIVOS DE SIMPLICIDAD AQUI SOLO SE DESCRIBEN LOS PARAMETROS DERECHOS DEL CORAZON. EL DISPOSITIVO ES CAPAZ DE FUNCIONAR EN MUCHOS DE LOS MODOS DISPONIBLES (VVIR, DDDR, DDIR, AAIR), Y TIENE PROVISIONES PARA MULTIPROGRAMABILIDAD, ALMACENAMIENTO DE DATOS, TELEMETRIA BIDIRECCIONAL, ENTRE OTRAS FUNCIONES ESTANDAR. EL DISPOSITIVO TIENE DOS ENTRADAS PARA MEDIR EL IVCT: UNA, QUE SEÑALA EL INICIO DE LA EYECCION (FIN DEL IVCT). EL INTERVALO DE TIEMPO ENTRE ESTAS DOS SEÑALES ES LA DURACION DEL IVCT, QUE ES PROCESADO POR EL MARCAPASOS PARA DETERMINAR EL INTERVALO DE ESCAPE, A TRAVES DE UN ALGORITMO DE CONVERSION SENCILLO, ANALOGO AL QUE ESTA DISPONIBLE EN EL ARTICULO ANTERIOR. LOS PUNTOS DE INICIO Y DE FINALIZACION DEL IVCT SE DETECTAN POR CUALQUIER COMBINACION DE SENSORES BIOLOGICOS EN FORMA DE PRESION, VOLUMEN O TRANSDUCTORES DE FLUJO.
