The pacemaker system as described with improved classification of physiological events and improved heart via this respect, based on dsp

摘要

An implantable pacemaker system or a different heart monitoring system with a is indicated by a combination of dsp - techniques and software - algorithms improved possibility, heart inner signals to classify. The implantable device has one or more to different signals, which are to be monitored, corresponding dsp - channels, corresponding to different signals, which are to be monitored. Each dsp - channel preferably reinforced the incoming signal, converts the signal from an analog to digital form, filters the converted signal, in order to provide a filtered signal, processed, the filtered signal in order to provide a slope signal determined from the filtered and the gradient signals, when a intracardiales event has been detected, processed and the steepness of the filtered signals over a predetermined interval of analysis, according to a threshold value - passage, and generates a plurality of to the signal corresponding wave parameters. The generated wave parameters, are further processed by a programmable algorithm, in order to the received event based on dsp - parameters generated to classify and then the insertion, the development or the presence of an unwanted state of the heart in the case of a patient or to monitor or. Furthermore, the system may for the delivery of a treatment, for the storage of data from the ..
