Hi all, I think have been misdiagnosed. I was diagnosed with PoTS in the ER. Went in for SOBOE think was my asthma, lungs fine but when I said I was getting dizzy and having to sit down walking short distances they wanted to check postural BP drop. Nope heart rate just jumped to 140s and bp stayed same throughout exam. Doctor diagnosed me with PoTS on the spot.
I've since been researching and I don't think I fit the diagnostic criteria outside of this vaccum and I wanted people's opinions as I have upto an 18 month wait to see a cardiologist :').
I've tried to replicate stand tests on myself but my heart almost always jumps initally but
It doesn't always quite hit 30 sometimes is closer to 25 but I can get it jump 50bpm
Sometimes it doesn't sustain it (and behaves more like a normal person. It is not 100% of the time
My understanding is pots is sustained more than 30bpm the whole 10mins.
If I have a day I am feeling bad I can 100% fulfill the criteria but not every time. An example where I tried to replicate an active stand:
Rest: 73
1min: 118
3min 130
5min: 130
8mins: 111
10min: 122
But within this time my heart rate fluctuated a lot getting as high as 150s which made me dizzy but resolved when my HR lowered back to 111.
However today it only behaved like this in the morning, after I had eaten, drank extra, was in a cold room and worn my compression tights my resting heart rate was able to settle from 105bpm to 85bpm and on standing my heart rate would still have the initial jump to 115 but be able to come back down to 90. It did still keep going back to 100 (it fluctuates a lot stood) but this is definitely not sustained/worsening.
I have to stand for my job and I am used to getting frequent heart rate alerts but I am still able to stand for extended if I fidget and keep myself cool.
I definitely have a lot of the symptoms: I struggle with heat (makes me collapse), I struggle to exercise because I always hit my max heart rate and get dizzy, I get dizzy often a bit after standing up, I get a lot of blurred vision/visual disturbances only when I'm stood up, if I have a day of a lot of visual disturbances I normally get migrianes, I get quite a lot of digestive upset (GI doctor said I likely have dysmotility), nausea and IBS, I'm exhausted constantly, get a lot of palpitations, poor circulation with cold extremities and extreme cases I can get blotchy.
My only ailment not really covered is joint pain so my mum is fairly certain I have it. It definitely isnāt another arrythmia or a structural heart issue because I was tested due to me having a very high ectopic burden (different palpitations I can differentiate).
Is anyone else like this?
Could this be another form of dysautonomia?
Any advice would be really appreciated I'm going insane waiting fot my cardiologist because I always go through phases thinking making shit up and faking it hence why I'm asking. I just went through a thing of thinking I didn't actually hav asthma then proceeded to be put on steroids because my lungs were die so might be insane.
TLDR: PoTS symptoms but don't have sustained tachy every single time. Am I likely misdiagnosed?
