The Neuropathic Postural Tachycardia Syndrome
Open accessAbstract
BACKGROUND: The postural tachycardia syndrome is a common disorder that is characterized by chronic orthostatic symptoms and a dramatic increase in heart rate on standing, but that does not involve orthostatic hypotension. Several lines of evidence indicate that this disorder may result from sympathetic denervation of the legs. METHODS: We measured norepinephrine spillover (the rate of entry of norepinephrine into the venous circulation) in the arms and legs both before and in response to exposure to three stimuli (the cold pressor test, sodium nitroprusside infusion, and tyramine infusion) in 10 patients with the postural tachycardia syndrome and in 8 age- and sex-matched normal subjects. RESULTS: At base line, the mean (+/-SD) plasma norepinephrine concentration in the femoral vein was lower in the patients with the postural tachycardia syndrome than in the normal subjects (135+/-30 vs. 215+/-55 pg per milliliter [0.80+/-0.18 vs. 1.27+/-0.32 nmol per liter], P=0.001). Norepinephrine spillover in the arms increased to a similar extent in the two groups in response to each of the three stimuli, but the increases in the legs were smaller in the patients with the postural tachycardia syndrome than in the normal subjects (0.001+/-0.09 vs. 0.12+/-0.12 ng per minute per deciliter of tissue [0.006+/-0.53 vs. 0.71+/-0.71 nmol per minute per deciliter] with the cold pressor test, P=0.02; 0.02+/-0.07 vs. 0.23+/-0.17 ng per minute per deciliter [0.12+/-0.41 vs. 1.36+/-1.00 nmol per minute per deciliter] with nitroprusside infusion, P=0.01; and 0.008+/-0.09 vs. 0.19+/-0.25 ng per minute per deciliter [0.05+/-0.53 vs. 1.12+/-1.47 nmol per minute per deciliter] with tyramine infusion, P=0.04). CONCLUSIONS: The neuropathic postural tachycardia syndrome results from partial sympathetic denervation, especially in the legs.

The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“It is believed that impaired sympathetic tone (as measured by norepinephrine spillover) reduces venoconstriction, leading to venous pooling in the lower limbs and splanchnic beds.24”

In the citing paper
“Features described in subgroups of patients include increased sympathetic nervous system tone (i.e., hyperadrenergic POTS),17 partial peripheral sympathetic denervation leading to relative central hypovolemia (i.e., neuropathic POTS)27 and low blood volume (i.e., absolute hypovolemia),28 which may drive some of the other hemodynamic findings.”

In the citing paper
“More commonly proposed causes include partial peripheral neuropathy (“neuropathic POTS”),19 a deficit in blood volume, abnormalities in the renin-angiotensin-aldosterone system (RAAS)20, physical deconditioning,10 autoantibodies targeting peripheral adrenergic receptors21 and a hyperadrenergic state resulting from central activation of the sympathetic nervous system (“HyperPOTS”).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
