That's what I was thinking too, MVPS. I've had a couple of patients with the symptoms you've mentioned. Apparently the syndrome consists of MVP,NCS,headaches,fatigue,chest pain,palpitations,SVT,PVCs. Some physicians will say that none of the symptoms are related because there are many who have MVP and have no symptoms whatsoever, and there are those who have these symptoms with no MVP. I think it could be because we have not yet found the physiological connection between everything. And of course there are the physicians (and others) who just see a hysterical woman, and because nothing concrete can be found, it must be all in your head.
I have seen pacers used with NCS that have been successful in controlling the symptoms and I have also seen it used where it hasn't. That alone tells us there is something else going on that we haven't put our finger on yet. (implantation of a permanent pacemaker is generally a very safe procedure. But as Matt stated there can be complications but these are rare).
With one patient, the doc ordered Florinef, TED stockings, and increased fluid intake and it worked. Dehydration, even mild, can exacerbate the condition for some.
It sounds like you've had appropriate diagnostic tests, but have you ever had a tilt table test? That is supposed to be the gold standard for diagnosing NCS.
Beta blockers are used because of the increased adrenergic activity that accompanies this syndrome, hence the PVCs or SVT. In NCS there is a malfunction in the nervous system.
No matter what, I feel that if you present to the ED with CP etc. you should still be treated as a r/o MI and have the same diagnostics as everyone else. But that's just me.
Along with the beta blockers, SSRIs (like Prozac,Zoloft) maybe ordered. Now don't freak out, it doesn't mean you're crazy. The SSRIs have been found to work in some with controlling the symptoms.
Here are a few sites I found that ight help you out. At the very least you'll know you are not a crazy,hypochondriac female.
Good luck, and keep us updated.
