Exercise test and settings

Hi All, Had an eventful day with three treadmill tests to help determine the proper settings for my Adapta duel lead P/M. Key ingredient was turning down the upper sensor rate setpoint(from 85 to 48) This setting was preventing my h/r from increasing in the normal range. During the second run my rate easily went to 150 and went down in a normal period of time. We had the optimization on for the first test and turned it off for the second one to "freeze" it in position. Third run was with the r/r off and I achieved 130 plus with ease. Doc says he saw a few double beats though.(I usually see them after a good work out and they are far and few between) I had the r/r off for six weeks after my implant and had no problems.
My concerns are .............Should the h/r go up that fast ? and in a two hour tennis match will there be a problem over time?
Should I beg to get the r/r turned off? Am I inviting a/fib as it could show up as an exercise induced episode. Currently on b/b the night before tennis matches in small doses of .06 atenolol. Will get some form of a-fib (120-130) once a week which will abate within the hour............I will know more thurs. as I have a match. In running after the tests I achieved 150 h/r within 100 yards.

Thanks to all of you,and Bill, if you need other settings let me know.

Thanks for the heads-up. Why in your opinion would the doc not want to turn off the r/r. He has given me the impression that I was chronotropically challenged but the test showed negative. My previous doc reluctantly turned it off and all was well,( but I was on strong dose of b/b and my heart rate stayed low when exercising) so I had it turned back on..............
Could be trying to get me back on b/b.............
Thanks, Phil

You had a busy day!

Sounds like they were very thorough. Its not unusual to have a couple of extra beats or PVCs in the cool down phase after exertion. Even "normal" people can have them. I'm almost normal, sometimes, and I get a couple of bumps in the cool down, but not many and not everytime. :)

Rate response and double beats

If I am reading your comments correctly the double beats are actually extra beats. Atrial pacing with RR will not affect extra beats as the pacer can only create beats. It has no way of inhibiting beats. If you get a normal HR increase without RR it is definitely better to have it off. The result is a much better match to your bodies needs.
