pacing from yawning? and Raynauds

Hi everyone!
Just a question, actually 2 questions before I see my doc:
Is pacing (for those of us who know when we do) common after stretching/yawning? Is it triggered by the motion, or breathing pattern associated with it?
Also, since my Raynauds syndrome has reappeared out of the blue ( 4 new episodes) after a decade or 2 without it, I will be seeing my family doc. I think this is not a problem related to the syncope/PM, but thought I'd check with "the Club." Might just mean a new lupus flare.
Thanks in advance for your helpful info.

I can make my HR increase slightly by breathing deeply or fast. I pace off my own rhythm, not by the rate response function. I suppose any "activity" could trigger the rate response.

Hello,

I don't know that I'll answer your questions, but I will comment, for it may be worth.

"Is pacing (for those of us who know when we do) common after stretching/yawning?"

It could be, or it could not be common. It depends on what your heart rate decides to do after the stretching or yawning. If it falls below the minimum setting on your pacemaker, then the PM should step in and bring the HR back to at least the minimum setting. On the question of "is it triggered by the motion, or breathing pattern associated with it," The answer could be yes, especially if you have a PM that has the rate response feature activated. In this case, almost any type physical activity that can trigger the PM into thinking you need a faster HR to accommodate the perceived demand for a higher blood flow by your body will cause the PM to increase your HR..

As for your comment about Raynauds syndrome having or not having an effect, I certainly do not know. I can see where the contraction of the blood vessels in a person's extremities could throw a PM into a real tizzy, and I have been told altering blood flow patterns can be a cause of syncope. So I agree, that is a question for the good doctor.

One other comment. You mention feeling your PM. If this is a problem for you, fine tuning of your PM should stop this. More often than not, from what I can learn, this is caused by the power settings on the PM being higher than necessary.

Good luck,

Smitty
