Functional differences in brain of patients with <b>postural</b> orthostatic <b>tachycardia</b> syndrome (<b>Postural Tachycardia</b> Syndrome) (Umeda et al., 2009). (A) Differences between controls and <b>Postural Tachycardia</b> Syndrome patients in resting heart rate and evoked responses to neutral and emotional stimuli, characterized by accentuated prolonged cardiac acceleration in orienting response with lack of emotion specificity. (B) Differences in regional brain activity between <b>Postural Tachycardia</b> Syndrome and control participants showing exaggerated withdrawal of activity within ventromedial prefrontal cortex in <b>Postural Tachycardia</b> Syndrome patients when encountering emotional or neutral stimuli.

Schematic cartoon of sinus <b>tachycardia</b> disorders spectrum. <b>Postural tachycardia</b> syndrome (POTS) patients have greater sympathetic tone (SNS) and less parasympathetic tone (PNS) than healthy subjects. Patients with inappropriate sinus <b>tachycardia</b> (IST) patients have even greater SNS tone and lower PNS tone compared to POTS patients.

Vasoconstrictive effect for the combined POTS groups. The vasoconstriction for the combined POTS groups was significantly greater than in control subjects. This constriction was enhanced with withdrawal of β2AR‐mediated vasodilatation with ICI‐118551. Prazosin reversed this to baseline. No significant vasoconstriction was observed for the control subjects. AR indicates adrenergic receptors; POTS, <b>postural tachycardia</b> syndrome; PRAZ, prazosin.

Acrocyanosis in POTSOne of the more striking physical features in the <b>postural tachycardia</b> syndrome (POTS) is the gross change in dependent skin color that can occur with standing. The panel shows the legs of 2 people who have been standing for 5 minutes, a healthy control subject (left) and a patient with POTS (right). The patient with POTS (right) has significant dark red mottling of her legs extending up to the knees while standing, while the control subject does not have a similar discoloration.

Distribution of test results.Abnormal results are displayed within the lightly shaded region. The 9 individuals that meet criteria for neuropathic POTS (abnormal skin biopsy and 1 other abnormal test) are in the darkly shaded region. A total of 9 subjects had abnormal intra-epidermal nerve fiber density (skin biopsy). A total of 12 individuals had abnormal quantitative sensory testing (QST). A total of 8 individuals had abnormal sudomotor (QDIRT) testing. * = individuals with neuropathic POTS, † = individuals with cholinergic POTS.

The receiver-operating characteristic (ROC) curve of the Logistic multivariate regression equation for predicting the likelihood of POTS.The longitudinal axis represents sensitivity to predict the probability of POTS. The transversal axis represents the false positive rate (1-specificity) of the prediction. The 45° gray line of the graph stands for reference line, representing sensitivity being equal to false positive rate (e.g., does not have the predictive value completely). The red curve is farther from the reference line and nearer the upper left corner of the graph. Area under the curve was 0.839 (95% confidence interval: 0.786 to 0.891; p<0.001).
