unsolved rapid heartbeat

[lnglgz7]

Hello!
I am asking for anyone to help me.  I am a 21 year old female, 6 feet tall, 120 pounds (NO I'm not purging) who has recently developed a rapid heart rate-sometimes over 180 beats a minute, usually when I am at rest.  I have sudden blood presure drops to the point that my pulse can be lost and I come close to passing out.  I have had every blood test under the sun with all tests coming back normal.  I have had holter moniters, tilt table tests, echo cardiograms, chesk x-rays, MRI and CT Chest scans, ekgs, etc....everything shows normal except rapid heart rate when I rest.  Before I get this, I usually feel this rushing, warm feeling pass through my body starting at my toes making it's way to my head.  I feel this is coming from something else than my heart-maybe chemical or hormonal.  I also have Intercystical Cystitis and Endometriosis. When I was 16, I was put on Femara, a cancer drug, to stop the estrogin that grows the endo and I was did not have a period for 9 months while undergoing this treatment.  At the end of the nine months, I had to be pulled off the treatment because I devolped migraines and tunnel vision.  I did have a base MRI of my brain-with normal results.  After that episode, and being pulled off the meds, I got better for a while.  NOW THIS!  I don't know what to do and no docotor has been able to give me an answer.  I do notice the heart symptoms get worse about a week before my period and sometime get bad after certain foods I eat.  My heart goes so crazy that it wakes me out of a sound sleep.  Is there any rare condition that the docotor's could be missing with these symptoms or is there anyone else out there like me?  Please let me know your thoughts ASAP-I need an answer or even a general direction to start looking in!!!

hmmm, idk but your weight could just be another smptoms of something going on in your body,,, it's extremy  unhealhty. I'm suprised you didn;t talk about it more, it looks like it would be  a very importnant factor in your problem, but anyways, i sympathize asnd wish u the best of luck.

Your blood work came back normal?  Did they detect any anemia?  If your are anemic, that may cause rapid heart rate.  Are you on the thin side?  Your weight sounds a little low for your height.  What do your doctors think about your weight?  May want to look into this.  Hope things get better.

i've had such a similiar experience. I am 21 as well and out of the blue started having very fast heart beat of 160+ with several ER visits, had every test out there including an EP study, a month long event monitor, etc. everything came back ok except that i have sinus tachy...a normal but fast HB, very frustrating and discouraging. I would much rather there be soemthing wrong then not finding something and having to just deal, it that makes sense.

i've had high BP since i was 18 after a stint with diet pills and after ending that i to this day at 21 take 4 bloodpressure medications, basically my condition is a medical mystery.

I've given up on finding a cause for my fast HB just because i end up feeling discouraged when nothing shows up.

Good luck to you, I hope that something is figured out soon so you can have peace of mind.

I have had a similar experience as you. I am a 25 yr old female and suffer from a rapid heart rate. At times my heart slows down to the point where i feel faint. I have had EKGs Echo and holter done but everything was normal. I had another episode last night where i was asleep and woke up because my heart started pounding and i had a funny feeling in my body.  The doctors think it is stress but i am not sure. They want to do another holter on me but i worry that it will not show because these palpitations happen far apart. At times i wonder if it is hormonal because there is nothign wrong with the structure of my heart.

Sounds like you've been through a rough time, and I sympathize with you.  I would have to say go for another opinion, although starting from the beginning is rather daunting.  The question of hormones affecting heart rates comes up really often and it certainly seems to have an effect.  I know I get hormonal migraines for a week before and two days into my period.  I’ve had my hormone levels tested at different times of my cycle and the results are quite staggering in how they differ, so I believe strongly that our hormones play a big role in our heart issues.  I hope you get the answers you are looking for and feel better soon.

This has to be so frustrating and scary. I think that I would go to get a second opinion or third or whatever till someone (preferably a specialists) could give me answers.

Did they rule out SVT as the culprit?
