The atrial defibrillator includes a first detector for detecting atrial activity of the heart and an atrial fibrillation detector responsive to the first detector for determining when the atria of the heart are in need of cardioversion. The atrial defibrillator further includes a pacing output circuit responsive to the atrial fibrillation detector for pacing the ventricles of the heart at a pacing rate when the atria of the heart are in need of cardioversion and a cardioverter stage for applying the cardioverting electrical energy to the atria of the heart …

Why it's free to use
- Filed October 19, 1993 and granted July 24, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 19, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 19, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
