Catheter for mapping electrophysiological activity within a human heart spatially

摘要

(57) Abstract Mapping of the electric physiology activation inside the heart of the human is achieved with the utilization of the catheter (32) concerning the field of the myocardial inside layer. This catheter (32) at least has had the orthogonal sensor (34 or 46) of the pair which lays out in this catheter. These orthogonal sensors (34 or 46), paralleling to the catheter (32), in the catheter (32) lap having possessed the electrode which is almost laid out in direction 1mm or 5mm at the respective dot of the fixed longitudinal direction which leaves, receiving the signal which is taken difference in inside the differential amplifier (50), the section generate the signal which shows only the bio potential heart activity which is restricted at the specified dot of the myocardial inside layer. The orthogonal sensor (34 or 46), in the stimulus tip/chip (58) of the catheter (32) adjoining being laid out, while sending the energy which is in the midst of peshingu treating or in the midst of excising adjoining or contacting the stimulus tip/chip (58), or, the section makes the detection of the heart activity which is restricted possible. This section detection of the activity which is restricted, occurring simultaneously with peshingu or excision, intense or tries to be able to record the electrocardiogram of the system which is excised.
