Pacemaker tracking during exercise - can it be adjusted?
had a really good conversation with a new EP technician last week and he explained a lot and is very open to changes. He was very patient and let me ask a lot of questions.
I could sense he was busy so I let him go before asking him to explain one point he said that I have since looked up and still struggling to understand.
He said that he could see I was getting my heart rate up nicely and that it "was tracking consistently at 1:1". I know that 1:1 to means that for every atrial event a ventricular event was occuring.
What I did not appreciate is that I think he meant the pacemaker was doing this and that it can provide me with a ventricular beat at heart rates probably as high as I need (180 to 190ish).
I have no idea if my block is present during exercise (I suspect it is not) but I assume at this stage they do not want to take any chances.
I am now certain that during exercise (I have now been running 3 times a week since January) I am not as efficent as before the pacemaker was fitted. I'd say I'm about a third less efficient than I was only four months ago. I strongly suspect that this is primarily due to the ventricular beats during exercise being forced by my settings to be tracked by the pacemaker rather than allowing my intrinsic beat to activate. I suspect the paced beat during exercise is not as efficient as my own beat, assuming it is present during exercise.
When I next go back to the EP technician what options do they have to reduce this forcing of the ventricular pacing during exercise assuming I do not have a block during exercise?
I've started reading the section on PVARP in the Medronic but I do not understand all the terms yet so cannot make head nor tail of what it is saying.
I know you might say I might have a block during exercie but for the purpose of this discussion let's say I do not to keep things simple.
