michealdul Posted August 3, 2015 Report Share Posted August 3, 2015 Hi there,reading about the diagnosis of Postural Orthostatic Tachycardia Syndrome I got a little bit confused about the exact definition.Key is the increased heart rate of more 30 bpm within 10 min or alternatively more than 120 bpm in total.I am wondering "for how long" does the heart rate has to stay at the elevated level? Does every healthy person has an increased heart rate after standing up? Has the increase in heart rate to be somehow "sustained" to suggests PoTS? If so, what is sustained?

Katybug Posted August 4, 2015 Report Share Posted August 4, 2015 I don't think I've ever read that there is a minimum amount of time for the tachycardia to last. While most people do have some temporary change in hr during an orthostatic change, I think it is usually less than 30 bmp and or under 120 which is why that is the determining factor in diagnosing POTS.

Bigskyfam Posted August 4, 2015 Report Share Posted August 4, 2015 Every person sees a rise in hr when changing position...ours happens to go higher fluctuate or stick for lack of better words Quote Link to comment Share on other sites More sharing options...
michealdul Posted August 4, 2015 Author Report Share Posted August 4, 2015 That means a single rise of more than 30 bpm in heart rate - even if the heart rate falls down fast after 1-2 min. - would be recognized as POTS? Healthy persons would never have a rise of 30 bpm or more, that is what I understand? Quote Link to comment Share on other sites More sharing options...
MomtoGiuliana Posted August 4, 2015 Report Share Posted August 4, 2015 It may depend on the doctor's opinion, from what I have seen here with TTT results and doctor interpretations. I would think a good doctor would consider any orthostatic hr and bp fluctuations in light of additional symptoms. eg, if the patient also feels fatigued, etc that is a sign of orthostatic intolerance/POTS. In my experience, when I am experiencing POTS symptoms, my hr on standing is pretty sustained. But it also depends on the time of day. I have more orthostatic intolerance in the AM than in the PM. So I might not meet the clinical definition of POTS at 5 pm yet I do at 8 AM. Quote Link to comment Share on other sites More sharing options...
tgleiker Posted August 4, 2015 Report Share Posted August 4, 2015 From what my Neuro said regarding differential diagnosis is when there is a drop and also a drop in BP it could mean that you are having a Vasovagal response rather than POTs. There are differential diagnoses as such, but I know that they were checking me for that because my HR had dropped at one point, but then most of the time now it is sustained for a period of time hence the POTs diagnosis.
