vagus nerve and arrythmias

I have a terrible problem. I feel like I am about to kick the bucket. I have horrible arrythmias when I have the urge to defacate and when I attempt to defacate. I become very lightheaded, fain, sweaty, and my heart races out of control. Help me! I take a beta blocker, but it doesn't help. Can I do something about the vagus nerve to get rid of this problem?

I take Prevacid and my family doc says it quiets the vagus nerve.  Avoid spicy foods, try to have regular bm's.   Maybe a stool softener would help or anything that keeps things moving.  Anything that affects my digestive system affects my heart and produces irregular beats.

Everything you describe sounds like the full spectrum of an anxiety attack.  A possible issue is that you've conditioned yourself to become anxious when you have those feelings.   It’s a behavioral conditioning.  This would mean that the anxiety isn't being caused by something in your autonomic nervous system.

For the prevacid, I thought that  is a proton pump inhibitor?  I don't think the action is based on effects of the vagus nerve, it blocks an enzyme in the gut to prevent acid production.  I could be wrong.

It does inhibit acid production, but it works to keep my irregular beats under control.  I am not sure how it works, maybe because I have reflux and when the acid backs up into the esophagus it irritates the vagal nerve.  If I skip the Prevacid I have more PAC's.  My family doctor and my cardio both agree, a vagal reaction can cause the "skips."  My heart problems have always seemed connected to digestive problems.

I'm interested in the anxiety conditioning you mentioned.  I think I do that.  If I'm alone and without my cell phone, I panic, sure that this time I'll have an Afib episode and won't be able to call for help.  When I distract myself, do deep breathing, or remind myself that it hasn't killed me yet, the panic melts away.    I have, however, went from a big irregular beat straight to panic mode without any thought process whatsoever, it's like a knee jerk reaction.

Any other ideas on how to "de-condition?"
