Abstract

SISTEMAS Y METODOS QUE UTILIZAN UNA RED (20) DE MULTIPLES ELECTRODOS (24) DISPUESTOS PARA LA ASOCIACION FUNCIONAL CON UNA REGION DE TEJIDO CARDIACO QUE FUNCIONA EN COMBINACION CON UN SEGUNDO ELECTRODO ITINERANTE (36) QUE DESARROLLA UN MOVIMIENTO RELATIVO A LOS MULTIPLES ELECTRODOS PARA SU ASOCIACION FUNCIONAL CON DIFERENTES REGIONES SELECCIONADAS DEL TEJIDO ENDOCARDICO DEL INTERIOR DEL CORAZON. UNA UNIDAD ANALOGICA O DIGITAL DE PROCESAMIENTO (32) ACONDICIONA A UNO DE LOS MULTIPLES ELECTRODOS Y AL ELECTRODO ITINERANTE PARA EMITIR UNA SEÑAL DE ESTIMULACION MIENTRAS QUE OTRO DE LOS MULTIPLES ELECTRODOS Y EL ELECTRODO ITINERANTE REGISTRAN LOS ELECTROCARDIOGRAMAS GENERADOS COMO CONSECUENCIA DE LA SEÑAL DE ESTIMULACION. SE INTRODUCE UN PATRON DE EPISODIO CARDIACO DE DIAGNOSTICO CONOCIDO DETECTADO CON EL SISTEMA DE MULTIPLES ELECTRODOS. SE INTRODCE UNA MUESTRA DE EPISODIO CARDIACO GENERADO MEDIANTE LA ESTIMULACION DESDE UNO DE LOS ELECTRODOS ITINERANTES Y DETECTADA CON EL SISTEMA DE ELECTRODOS MULTIPLES. EL ELEMENTO Y EL METODO DE PROCESAMIENTO COMPARAN ELECTRONICAMENTE LA MUESTRA CON EL PATRON Y GENERAN UNA SALIDA.
