PM dependent expectancy

Sinus node bradycardia. When I got the pm 3 years ago, my natural heartbeat was working 60% of the time. Yesterday I learned from the interrogation that my natural heartbeat is now working 20% of the time.  What’s next?

We never know what's around the corner. Some people progressively use the pacer more and more. Some go up and down. Some mostly stay the same. If you feel good, you are pacing the right amount. Some of us pace every beat from the second it was turned on. 

Were your settings changed when the number went up so much? If they changed your limit so the pacer kicks in sooner, you would pace more but likely feel better so it's all good. There is no one number that's considered good or bad. They set it to pace enough for us to be safe and feel good. 

Don't get hung up with the numbers

Don't get hung up with the percentage numbers.  I pace 80-90% but remember, they have my heart rate set at 60 BPM. So that means the pacemaker is going to kick off most of my heartbeats because I wouldn't be going that fast of rate most of the time. Which means those numbers will be high.  Unfortunately I probably was getting along at the low 50's with my natural heart beat and occasionally dropping down into the low 30's - which is another reason why I got the pacemaker in the first place.  So you always have to take those numbers with a grain of salt.  They don't give you the whole picture by themselves.  

Another thing is the pacemaker has to do calculations to get those numbers so the longer you go the more accurate they are.  When I first started pacing it showed me pacing 40% of the time.  The the number changed as more time went on.  Now it's in the 80-90% range but that's after six years and with the rate set at 60 BPM.  

You pace what you pace and the numbers are going to be what they are. As long as you're feeling OK and the EP isn't concerned I wouldn't worry about it.  
 

Thank you TheKnotGuy

Thank you theknotguy. 

My intrinsic hr is 28. It was 30 when I got the pm. 

The pm is set to 70, and then to 60 from 10:00pm to 6:00am.  I feel ok. I guess the answer is the pm percentage could be at 100%, as long as the underlying bradycardia sustains itself. 

You know you're wired when...

Your heart beats like a teenager in love.
