Under- sensing , over- sensing , and off-line sensing method and its application in the noise of detection

摘要

A system and method for performing an independent off-line evaluation of the events sensed about the collected electrogram , and use the steps of sensing the electrogram using an implantable medical device (IMD), a multi-pass process by determining the position of the heart in at least one channel of the electrogram by the steps of generating a group of multi-path beat position , and storing electrogram and the device identification beating position in the memory location the system and method includes the step of retrieving from the electrogram and device identification beating position memory location . Multipath process determines the position of the heart in at least a first channel of the electrogram . Subsequently , the device identifies a group of beat position is compared with the multi- path group beat positions are identified using a multi- pass method . Based on the comparison step , an excess of sensing beats , it is possible to detect the noise from under- sensing device or the beating .
