For a little over a year there has been this lingering question mark over my head asking if I have Postural Orthostatic Tachycardia Syndrome, or POTS for short, a form of Dysautonomia. I had a couple medical practitioners say that they suspected POTS. POTS is defined as your pulse going up at least 30 bpm when you stand up then sustaining a high pulse for a little while (but the length of sustaining is what confuses me.)
I got myself a pulse oxygen meter that clips onto my finger in order to see what happens to my pulse when I stand up. About half of the time my pulse does shoot up at least 30 bpm, often way more than that. Sometimes it stays that high for a minute or two, but normally what happens is my pulse shoots up, then goes down, then goes up again, then goes down again, then goes up again... it's a roller coaster. I took some videos of this happening and sent them to a Neurologist in New Hampshire who is an expert in Dysautonomia that my primary doctor referred me to. He took me on as a patient, which was a huge relief to me since he's very difficult to get into.
Why not see someone locally in North Dakota? Because POTS isn't well understood, and it takes a doctor with training in dysautonomia to be able to diagnose it. There isn't anyone in ND except for one pediatric doctor that diagnoses, and I'm not a child. There doesn't even appear to be a Tilt Table in ND. If I went through the local hospital for a referral they would have sent me to Mayo in Rochester, MN. It's an 8 hour drive from here, and very expensive. Too expensive compared to flying somewhere to see a highly rated dysautonomia specialist.
On the trip to NH I also scheduled a Tilt Table Test, a Echocardiogram, Lyme Disease testing, a visit with the Neurologist, and a visit with my primary doctor (my Naturopathic doctor.) It was a very full trip. In preparation for the visits I had to be off all my supplements for a few weeks prior. I posted a bit about that experience, but in short, I didn't do quite as badly as I expected without the supplements, but I did get worse. High adrenaline and crashing during the day, high adrenaline and interrupted poor sleep at night. My digestion became poor and my joints and muscles ached. I ended up gaining between 10-15 lbs (lots of fluctuation day-to-day.) My mood deteriorated rapidly, and my periods became irregular. My stress level was through the roof and I couldn't control it, even while relaxing.
On the first day of the trip I went to Elliot Cardiology in Manchester, NH. I started with the Tilt Table Test. I had to fast at least 4 hours before the test to make sure I didn't vomit during the test and end up choking on it. As someone who has to eat every 2 hours to stay strong enough to function, that was hard, and then the test took about an hour. After the test my blood sugar was 72, which was barely above hypoglycemic, so I was actually impressed with my body that it didn't get hypoglycemic after all that, but I was very shaky.
The test was... not really what I was expecting. I was strapped down to the bed. It took 3 nurses to find a vein in my arm to put an IV into - the IV was to raise my blood volume back up with saline in case my blood pressure dropped too low. They almost gave up on using my arms for the IV, but the last nurse they called in wasn't afraid to dig a little deeper and she managed to get the needle into my vein. They hooked me up to an EKG machine, and took my blood pressure. I was expecting that they would let me lay calmly for a while to get my body down to baseline, but next thing I knew, I was being tilted upright on the bed. I definitely was feeling nervous and high strung, definitely not at my baseline before they tilted me. I started to get upset because I didn't feel like they were doing the test right, but the tilting made me feel so weak that all I could do was focus on surviving the tilt. In that moment I understood why POTS patients say the TTT can be really painful and difficult to endure. During the tilt I felt this deep pressure moving downward in my body, my vision narrowed towards black, and I started crying. Tons of tears just poured out and they had to give me tissues. It was horrible - but a feeling I was familiar with. I've felt like that before when standing up too quickly, but this was the most extreme. I'm not a fainter, my body always fights the feelings like I'm about to faint. If I was a fainter, that's when I would have fainted and I would have passed that test criteria. I couldn't communicate well, Thoughts were not working well, so when the nurses asked how I was doing, I just got out the words "weak, I can't stop crying." But then I was standing there strapped to this bed at an 80ยบ tilt. Within about 5 minutes I felt better. My body was recovering. I didn't understand what to do - I felt well supported by this bed, so my body wasn't working to stay upright. I had no idea if I was supposed to relax all my muscles and stop supporting myself or if I was to stay there, legs locked upright. I had waves of hot flashes, waves of weakness, but never fainted. One nurse told me, "You're not quite normal," and I never had a chance to ask her what the meant. After the test she had to run before I could question her.
After 30 minutes they laid me back down flat. This is the part that's as bad as the tilt itself. I was able to stand up, but was very weak and shaky. I was trembling. I talked to the nurses for about 30 seconds, then I tried to take a step. I couldn't. My leg muscles gave out and I had to fall back down on the bed. I was crying hard again, shaking almost violently, freezing cold, and felt so weak. The nurses argued a bit about if it was an anxiety attack, hypoglycemia, or adrenal issues. The one nurse was sure it was adrenal, but they're not allowed to diagnose. That's when they took my blood sugar and found I was borderline hypoglycemic. On this note, I was disappointed that they did not do the version of the TTT in which they infused adrenaline through an IV if I didn't faint, and then do blood labs to see how my adrenals react to the IV. This part of the test often makes people faint, and then they know the syncope is from adrenal issues. I know I have adrenal issues, so I wanted that part of the test done and didn't get it.
I couldn't walk on my own, so they put me in a wheelchair and delivered me to the echocardiogram room. I needed the echo to check on the status of my Pulmonary Stenosis, which I've had since birth and it never went away. It's still there. That's about all I learned from the test. I'm thinking of sending all my past echos to a cardiologist there and having them do some comparisons.
That was the end of the first day of testing. I was weak and low energy the rest of the day.
The next day I saw my Neurologist at Dartmouth-Hitchcock Medical Center. But let me back up a bit: I almost didn't a couple of times. I got a phone call from his office the day before our flight out there saying that he wanted to cancel my appointment because the Autonomic Nervous System testing equipment broke and he couldn't test me. I had to beg to keep the appointment, even just a consult, and they agreed because I was traveling. The day of, I had two major strikes against me going: I started my period that day (I have to roll my eyes at my body choosing the worst times), and the weather was horrific. 3 inches of snow in a few hours time, icy roads, and near whiteout conditions. An hour and 20 min drive took us 2 hours, and I ended up getting there 10 minutes late. 5 more minutes and he wouldn't have seen me. Or so the receptionist said, but the doctor was forgiving and spent a good amount of time with me. I didn't have time to go to the bathroom before seeing him, so I was cramping badly and was uncomfortable. My blood pressure was 120 something over 63 and my pulse was over 100, if I remember correctly, which showed just how stressed out I was about my bathroom needs, getting to see this doctor finally, and being so rushed in bad weather to get there.
He sat me down and let me talk - he had me tell him my history and all my symptoms. He gave me a good amount of time and really listened, which blew my mind. He was amazing. He took me seriously, didn't try brushing off anything I said. He even knew about the damage vitamin b6 toxicity can do and understood what I went through with my nerve pain. He had me to do some nerve conduction testing, which turned out normal. He also showed me the results of the TTT:
I went up over 30 bpm, the criteria for POTS. But it doesn't say if it was sustained. It could also be POTS symptoms caused by something else. So he needs more information.We decided that since he wasn't able to do the autonomic nervous system testing that he would have me wear a heart monitor for 14 days - a Zio XT Patch...
...Which meant not being able to go back on my supplements. My doctor and I agreed that we need to measure my heart without the medical aids to show how I am without support. Today marked 14 days, so I ripped the monitor off and took a hot shower and my supplements. The patch was itchy the whole time and it left me this pretty rash:
I'll tell the rest of the story in Part 2, as I have to go to work now. :)
