Thanks. Does anyone have access to this paper? Haven't been able to find it online.
Where does the idea that >30bpm increase during tilt testing is pathologic came from? Does anyone know how this threshold was justified or where...
There were 252 participants in this study of which 123 in the age group of 18-29 (where POTS diagnosis is common). They only did 5 instead of 10...
There are more of these. Plan to write a blog post about it to summarize the main findings. Might have important implications for POTS and OI...
Think I've more or less found what I was looking for: Normal versus abnormal: What normative data tells us about the utility of heart rate in...
Looks like a highly problematic article, suggesting the opposite of what actually should be done to help patients. It refers to the Cochrane...
This is a historic paper from 1993 where POTS was first defined. I am very interested in reading what it says but do not have access to it....
Abstract To characterize the idiopathic postural orthostatic tachycardia syndrome (POTS), we reviewed the records of all patients aged 20 to 51...
Yes that is another big problem. But I meant something differently: a study that does tilt table testing in a representative sample of the general...
The supplementary file gives the following data (my bolding): Head-up tilt table testing at 70 degrees from horizontal for up to 40 minutes was...
This paper looks to be important for the origin of the concept POTS: Schondorf and Low labeled the condition “idiopathic postural orthostatic...
Thanks for sharing. It would be interesting to have data on tilt table testing in a large representative sample of the general population to see...
There author makes three interesting points about POTS in adolescents. The threshold for standing test should be lower than for a tilt table...
It's also a strange thing to study: whether making up an explanation for symptoms makes the patient feel less ill. I assume that the main...
Apparently, the symptoms are no longer medically unexplained. That seems to be the main message that they want to spread. In the introduction...
This is the primary outcome, the PHQ-15 [ATTACH]
Another flaw: just noted that the statistical analysis section says: "...no adjustments were made for multiplicity."
Looks like a highly problematic study. It has the design A +B versus A. The control group got no intervention at all, only the usual care that...
A critique of this study was published by Paul Garner, Alan Carson and others (but also George Davey Smith). They write: There are problems with...
The definition seems to be overly inclusive. It does not require any particular symptom, does not require any level of functional disability or...
Separate names with a comma.
