Open the CIPO recordAbstract From the Canadian patent
An R-wave detection system includes an electrode (12) for placement in close proximity to or in contact with a heart to sense electrical activity of the heart. A signal processor (16) is in communication with the electrode and is , responsive to receipt of the analog signal from the electrode to condition the signal to account for noise, and far field effects. The system is operative to determine whether the conditioned signal exceeds a dynamic threshold value and, if so, the system generates a synchronization pulse to indicate the rising edge of an R wave.

Why it's free to use
- Filed July 22, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 22, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 22, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
