Exercising with adaptive mode off

Hey-
I have a Medtronic CRT and it is pacing 100% of the time and does not have adaptive mode turned on. This means that even when I am exercising my heart rate stays at 85bpm. I have a couple of questions about this. 1. Do I still burn the same amount of calories when exercising or is it limited by my lower heart rate? 2. Will I be able to increase my aerobic threshold or not?
Thanks,
Thomas

Calories burned is a function of effort exerted. If your hr isn't going up, you are very limited in how much you can exert. You shouldn't be pushing too hard if your rate isn't going up. There's a reason why our rate goes up with exercise- because we need more oxygen. If it were me, I'd want it turned on.
Adaptive Mode

I am just afraid that if they turn adaptive mode on my rhythm could get bad again. A little background on me: I have had every bad heart rhythm you can possibly have; I have had to be shocked by the defibrillator portion of my device around 10 times; I have been shock free for the last 2 years ever since they set the pacemaker to pace 100%. Isn't it possible that if they turn adaptive on then my heart could get out of control again?
ask your dr, but probably not

I can see why you'd be nervous about it! Your doctor would be able to tell you for sure, but if it's all paced, it's not your heart initiating anything, right? Cardiac rehab might be a good option, test the waters under controlled conditions with lots of supervision.
Thanks

Tracy E-
Thank you for your opinions. I guess I might not understand how adaptive mode works. so when I'm exercising if it was on it is not stopping the pacing and letting it be natural it is actually still pacing but allowing the pacing to get higher? If that makes any sense.
Thanks,
Thomas
rate response
by Tracey_E - 2016-07-27 14:21:08
If rate response is on, it will sense that you are exerting and raise your rate for you by pacing faster. So still pacing but pacing differently, instead of pacing at a steady rate it's watching for when it needs to pace faster.
The pacer can only sense and pace. If you are beating on your own, it will sit back and watch (sense), or it can actively pace, that's it. The pacer has no way of preventing the heart from beating faster on its own. That's why I think it would be ok, because the heart could take off and go faster now on its own if something triggered it, and apparently exercising is not triggering it.
Adaptive Mode / rate response?

I am not sure what you mean by adaptive modes. The units have a number of different automatic and manual modes.
Some adaptive modes look for normal heart beat if not not then takes over. Other modes look for adnormal patterns and tries to stop them.
Rate response is a method that detects ativity and can increase the HR if the sinus nodes does not do this naturally.
There is a large number of adjustments on all of these parametes.
You need a long talk with your doctor to first find out exactly how and why you are being paced. Then questions about what modes are being used. What happened the last time that you got shocked. And what changes can be made.

Calories
by Good Dog - 2016-07-27 08:07:43
If you cannot get your HR above 85 bpm when exercising then yes, your ability to exercise is limited and thus, your ability to burn more calories is also limited.
You may be able to increase your aerobic threshold slightly, but you are really limited to light exercise only. Also, you probably will not feel good when you exercise beyond the point that your heart can maintain a sufficient amount of oxygenated blood.
If you want to exercise for maximum benefit and feel good at the same time you really should consider having the activity monitor turned-on.
