Pacemaker pacing percentage

I got my pacemaker August 4th and two weeks ago was told that I am pacing at 97%, before that in August it was 94.4%.  My heartrate is set at 60 for the lowest heartrate and I rarely went into the 50's before the pacemaker.  Why am I pacing so much?  Even the person who checked my pacemaker couldn't explain why.  Any ideas?  We called Medtronics but didn't get a plausible explanation.

If it's set at 60, it's kicking in every time your rate goes under that. It was probably in the 50's more than you think, or not going up on exertion. If you feel good, don't worry about the numbers. There is no number considered good or bad, if you feel good you are pacing the right amount. Many of us pace every beat.

If I am pacing 97%. does that mean that I really needed a pacemaker?

oh yes!

97% means 97 out of every 100 beats is paced. There's no doubt you need it.

Many thanks to both of you for your explanations!

Hi Terrace - please check out the search function on this site to see some earlier discussions on pacing % - there is much variability among the members here (I'm personally 100%, just as an aside).  Keep asking your medical team to answer your specific questions, in addition to accessing the great information here on this site.  Wishing you the best going forward.

As Tracey says, the paceing percentage number, by itself, means nothing.  If a perfectly healthy personn was given a pacemaker and it was set to 100bpm, they'd pace at nearly 100% too.  If our natural rate is 50bpm, and have pacemaker set to 60, same deal.

Many of us are paced every beat.  Unless paced, mine doesn't.

second that

i second what others have said but also be aware in simple terms there are two percentages,

atrial pacing and ventricular pacing.

The two are very different. I have no need for atrial pacing but as Agent86 points out if I was set to pace at a minimum of 60bpm, then my atrial pacing would be very high as I drop below 60 when asleep and that is perfectly normal.

My atrial pacing is negligible but my ventricular pacing is 100%. It is all associated with why your pacemaker was fitted and the subsequent settings.

hope that helps




Depends on which lead is pacing

When you say your low limit is 50 but pacing 94% and your heart rate never went under 50. My guess is this isn't the lead pacing 94%. You should have 2 leads. One should pace the top chamber and the other bottom chamber. If you have heart block then that would be all bottom chamber pacing. That 94% has nothing to do with the low limit of 50. You may not pace at all in the top chamber is my guess since your heart never went under 50. Pacing percent dose Not correlate with how much you really needed a pacemaker since we are all paced for different reasons and settings.
