Open the CIPO recordAbstract From the Canadian patent
An implantable cardiac rhythm management device 10 includes a microprocessor-based controller 28 adapted to receive digitized electrogram signals from leads 14 placed on or in the heart and incorporates an autosense algorithm which is called into play when an electrogram is detected that exceeds an event detect threshold ET and capable of adjusting a sensing threshold ST to improve detection of cardiac depolarization signals in the presence of noise. The sensing threshold is automatically set on a beat-to-beat basis at a level that is dependent on a predetermined percentage of the peak amplitude of a current and an immediately preceding sensed or paced beat. The event threshold ET, which is …

Why it's free to use
- Filed May 19, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 19, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 19, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
