I can help with this!
So firstly define what you mean by upper tracking limit? Are you referring to upper *rate* limit?
In any case this is all programmable and customizable. Most practices have standard values they like to set for upper and lower rate limits.
The only way to know what these are for your device would be to throw a device programmer on it and find out.
Alternatively you can look at the paper that prints out of the programmer when you go to your checkup.
Because your device is a Medtronic it’s possible that they have upgraded from the big blue computer looking units to a much sleeker smaller tablet. In which case you may not even get a paper print out; it may all be done digitally.
Sorry I got torn away a bit earlier!
I just wanted to expand a bit by clarifying what exactly tracking refers to vs rate limits
Atrial tracking refers to how your device “listens” to activity in the atria. If your atria begin to beat too fast as a consequence of AFib or pacemaker malfunction your device will “mode switch” and stop listening to the atria.
Rate limits refer to how fast your pacemaker will pace if you experience an increase in physical activity
There is also pacemaker “refractory periods” which help us control how fast your ventricles can respond to a high atrial rate by blocking out a number of atrial impulses.
These 3 parameters all come together to help program how fast you’re pacing and what mode you’re in.
However out of all the parameters the only one I could see necessarily being super relevant to a patient is the upper rate limit in general. “What’s the max I’ll pace at?”
Rather than reading the manual by the way I recommend you sign up for “Medtronic Academy”
It is a completely free resource from Medtronic for us healthcare professionals.
They have a basic pacemaker programming course which is 100% free and designed for the absolute beginner.
That may be easier than reading a manual..
