I had a CAEP test today with the device rep to see about fine-tuning to improve exercise output and endurance. Mine main issue has been cycling up hills, but I also have plateaued on jogging. He seemed quite impressed that I made it to the end, with a treadmill speed of about 5 mph. He plotted my data to give a graph showing that with the new settings I am right where I ought to be for exercising.
He made a few tweeks: increased my upper rate from 140 to 155 and turned on some sort of feature that allows a change in the AV setting, so that it narrows when my heart rate increases. It turns out my device doesn't have MV capabiltiy, which he indicated would be the best way to accomodate hill climbing. Oh well. And he made a change on my LV lead which will hopefully lead to less phrenic nerve stimulation. I'm not sure that was a good idea, because even though my belly isn't twitching, I can feel something is different.
And the rep was willing to answer lots of questions that others have just sort of brushed off. I found out that I have intermittant flutter. Also when I am in a Flutter, or a fib, the low rate setting is 70 to accomodate for loss of atrial kick. I can feel atrial arrhytmias and I wondered why my heart rate was higher then. He also interpreted some of the info from past interogation reports.
He said that most people don't care about that stuff, but I think from reading this forum, a lot more care than he realizes.
