Montior readings and persistant adrenaline rushes and pvcs

[dande4]

Hi, and thank you for taking the time to answer my question. I am a 34 yr female currently 8 weeks pregnant with two other children, previously diagnosed as having borderline MVP with trace regurgitation and a history since diagnosis of some extra beats (pac/pvc) and some several in a row. Since April of last year after a viral illness, I started to feel like my heart would stop for a moment. I went on a 24 hr monitor which reavealed nothing. I was then placed on a King of Hearts monitor which have shown pac, pv'c occassional tachycardia, always in sinus rythym. I know that stress and deyhdration, sugar and other factors play a role in causing these to happen. My question is that the most disturbing to me is a rushing feeling, like an adrenaline burst with my heart. I don't feel it beating fast, I believe I feel it when it slows down, almost like a tapping feeling. I have recorded those and at times it has shown within a few beats that my rate has gone up from appox. 60's to the 90's and back, within a few beats, and other times it shows nothing, but always in sinus rythym. I have been told not to worry that more than likely I am just overly sensitive to adrenaline and that it is a dysrrythmia not an arrhythmia. I have been on atenolol and switched to zebeta which I am now almost off since being pregnant. Otherwise b/p is usally 100/70 sometimes lower and feel well. Told seeing an EP was not necessary.

Is this common, as I was told it is?
Is it harmful?
Can your body just throw off to much adrenaline, inappropriately and cause all these strange sensations?
Just looking to put my mind at ease.
And are there two separate MVP issues and the one being just an imbalance in the nervous system?
Is that an electrical system problem?

Sorry for the length, but I appreciate your response.

1. Yes, quite common.
2. None of what you described sounds harmful.
3. Yes, adrenaline does this.
4. MVP is not an imbalance in the nervous system; that is just an incorrect theory thrown around on the internet and the lay press.
5. You do not appear to have a problem with your electrical system, based on the tests you have had.

A related discussion, Imbalanced nervous system with MVP more than a theory... was started.

A related discussion, adrenalin was started.

I have the EXACT same feeling with adrenalin rushes for no apparent reasons and arrythimias. I have been to every cardiologist on the block (including the Mayo Clinic) and forget it. No one has ever explained it to me. The best thing I can do when it happens is take a Xanax and wait for it to go away. I wish someone could figure out this adrenalin connection...

P.S., it can happen 1 time a day to 10 times a day and then not happen for weeks at a time.
