Unexplained Tachycardia - Help!
I am a 45 year old female. I have had SVT episodes my whole life, but over the last year they have become increasingly worse. I went in to a cardiologist and they dismissed my symptoms as they were not “life threatening”. After that, I was in the ER twice and was finally approved for an ablation. I had the first ablation in February. It was fairly extensive and they called it successful. Shortly after, I was back in the ER twice with more SVT episodes, however they were labeled atrial tachacardia. I felt horrible and my heart rate would rise to 140 or more just getting off the couch. On one of the ER trips, they put me on Flecanide and metoprolol and it was recommended to get a second ablation. These two medications relieved the symptoms to a tolerable level. I stopped taking it about 3 days before the next ablation in March per the Dr.s instructions. I went through the second procedure and they were unable to induce it and could not perform the ablation. They told me to go back on the meds and try a third one. I didn’t take any meds at all thinking maybe they were still in my system and that is why they couldn’t induce it the second time. They schedule the third one on May 2nd. Went through the whole thing again and they were still unable to induce it. My doctor is very frustrated and basically said he has no idea why this is happening. He called it possible POTS or Dysautonomia. He recommended Mayo for a consult. In the meantime back to Metoprolol. I am beyond frustrated and have no idea what to do. I also get severe migraines about once a week in addition to extreme fatigue all the time (I had this prior to my first ablation). I’m afraid to exercise at all because I get so winded and it is so uncomfortable to really do anything. I am so sick of hearing it is “not life threatening”. Maybe not but it is “life altering”. I was not like this prior to my first ablation, it was just the occasional episodes and few ER trips. Anyone have any thoughts or suggestions or similar experiences? Any help would be appreciated!

Boy, can I relate to this thread! I too experience SVT and PVCs a lot, resulting in many visits to the ER over the last 10 years. I've had echocardiograms and heart catheterizations, and I've worn heart monitors, which is misery for me, since I'm horribly allergic to the adhesive on the electrodes. Every time I have an EKG, it's the same thing: The tech doing the test pauses after looking at the reading, consults with the doctor, and then the doctor tells me it's normal, even though the test results say abnormal. When I ask the cardiologist about it, I'm told that the SVT and PVCs are normal and not something to worry about.
Turns out it's not that simple. Looking at the whole collection of symptoms and health problems I've experienced over the years, family history, test results, and medical studies, I believe that I may be suffering from POTS, Ehlers-Danlos, and/or dysautonomia (they're related). My niece has been diagnosed with POTS and EDS. I've been hyper-mobile ("double jointed") since I was a kid, but I didn't know it was a concern. I have tachycardia, as my mother did, but I've been told not to worry about it by various doctors. Dysautotomia could explain many of the other symptoms I've had over the years, all of which have been treated separately (ulcer, diarrhea, breathing problems, GERD, varying heart rate and BP, etc.).
Most doctors don't know a lot about these syndromes/diseases/disorders, which I think is why they've been looking for more common causes. The fact that I suffer from anxiety and depression (both symptoms common to POTS and EDS) has led doctors to see them as the cause rather than the effect. I'm trying to find a doctor who specializes in diagnosing these syndromes. I recently saw a neurologist at Johns Hopkins because of test results that show I have small fiber neuropathy, and I'm hoping he can refer me to someone who can do a tilt table test to see if it's POTS. I'm on so many medications that I'm at a point where I want to know what we're treating before I take on any more symptom-specific drugs.
Bottom line, I can really relate to the frustration everyone has expressed. What we are experiencing is real, and groups like this are so helpful to me when I sink into that pit of self-doubt that is inevitable when one is told over and over "You're fine" or "It's nothing to worry about." I get so tired of having to debate the reality of what's going on with my body, but I'm not going to give up. I'm stubborn that way!
Thanks to everyone for sharing your stories. It makes me feel less alone. Sending hugs and wishes for an accurate and helpful diagnosis for us all.
