The dynamic atrium detection sensitivity control in the pad possible medical carefulness bodily organ stimulus vessel

摘要

(57) Abstract Stimulating the heart electrically, being the pad possible medical application device (100) in order to pulsate, it has the detector (208 and 218) in order to detect the electric activity of the heart. The detector has the amplifier (210 and 220) which can adjust profit dynamically, between of atrium characteristic small motion increases the sensitivity for the electrogram. Replacing to that, it is possible also to do sensitivity control, by adjusting the limits value limit which it is related to the limits value detector which is included inside the detector dynamically. As for sensitivity level of the medical application device for the electrogram, also the rear of the pad adjustment of repetition is possible, desirably, when detecting the fact that normal cave room rhythm (NSR) is lost from inside the atrium of the heart, responding to that, it increases. This medical application device is calibrated by the assistance of the external calibration equipment (400), appropriate sensitivity level is decided. In addition, it calibrates the medical application device of the pad type which possesses adjustment possible sensitivity dynamically and operates, concerning the method of improving it is disclosed the sensitivity of the particular medical application device for atrium characteristic small motion.
