ABSTRACT:
There is provided an implantable cardiac pacing system or other cardiac monitoring system, having an enhanced capability of classifying intracardiac signals through a combination of DSP techniques and software algorithms. The implantable device has one or more DSP channels corresponding to different signals which are being monitored. Each DSP channel provides for amplification of the incoming signal; conversion from analog to digital form; digital filtering of the converted signals to provide filtered signals; operating on the filtered signals to provide slope signals; determining from the filtered and slope signals whenever an intracardiac event has been detected, e.g., R wave, P wave, etc.; and signal processing of the filtered and slope signals for a predetermined analysis interval after threshold crossing, for generating a plurality of signal parameters. The thus generated signal parameters corresponding to a signal are further operated on by a programmable algorithm to classify the detected event based upon the DSP-generated parameters. By this combination of digital signal processing and programmable software coordinated with each DSP channel, enhanced intracardiac signal classification is achieved.
