Open the CIPO recordAbstract From the Canadian patent
Some false tachy detection prevention algorithms miss blocked 2:1 sensing and therefore miss some true tachy situations. Here an algorithm that uses sensed far field R waves to determine whether to search for blocked 2:1 sensing is implemented and a search algorithm is also described.

Why it's free to use
- Filed September 13, 1996 and granted December 9, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 13, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 13, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
