have paroxsymal atypical atrial flutter and have a pacemaker implant with the heartrate set higher than my underlying natural heartrate.

My cardiologist states that he hopes that this pacemaker setting will prevent the rogue heartrate being allowed to step in. I have until recently been free of any instances of irregular heart activity for 5 years - so the logic is undoubtedly sound.

However he states that if atypical flutter does manage to creep in, the pacemaker will close down until sinus rhythm is detected so as to prevent conflict. However following a recent instance of AF the hospital detected that the pacemaker was pacing me whilst in AF.

In addition to the PM I take 5mg Bisoprolol daily and Warfarin.

Does anyone else have such a setting on their pacemaker?
