DISPOSITIVO DE DETECCION INTRAVASCULAR

SISTEMA PARA DETECTAR LA ACTIVIDAD ELECTRICA EN EL INTERIOR DEL CORAZON DEL PACIENTE, QUE COMPRENDE UN MECANISMO INTRAVASCULAR ALARGADO (10) COMO UN CATETER O GUIAHILO, QUE TIENE AL MENOS UNA PAREJA DE ELECTRODOS BIPOLARES (17,18) EN LA SECCION DISTAL (12) DEL MECANISMO ALARGADO PARA DETECTAR DE FORMA INTRAVASCULAR LA ACTIVIDAD ELECTRICA EN EL INTERIOR DEL CORAZON DEL PACIENTE. EL CATETER O GUIAHILO TIENEN UN CILINDRO TUBULAR PREFERENTEMENTE (14) FORMADO POR CABLES TRENZADOS, QUE INCLUYEN UNA PLURALIDAD DE CONDUCTORES AISLADOS (15) QUE ESTAN ELECTRICAMENTE CONECTADOS A LOS ELECTRODOS BIPOLARES (17, 18). A method and system for detecting electrical activity within a patient's heart, particularly the electrical activity which causes arrhythmia, which includes a first intravascular device such as a catheter or guidewire having a plurality of sensing electrodes on a distal portion thereof which is disposed within one location of the patient's coronary vasculature and a second intravascular device such as a catheter or guidewire having a plurality of sensing electrodes on a distal portion thereof which is disposed within a second location of the patient's coronary vasculature to facilitate mapping the electrical activity of the patient's heart. Once the electrical activity has been mapped, therapeutic procedures can be initiated.
