Postural orthostatic tachycardia syndrome: A conundrum for patients and healthcare providers.
Holly M Cline, Adam Einhardt
PMID 34928881WHAT IT FOUND
POTS is diagnosed by a sustained standing heart-rate rise of at least 30 beats/minute without hypotension.
Care is symptom-focused: fluids, salt, compression, graduated recumbent exercise, off-label medications, and suicide screening.
Key findings
01POTS is diagnosed by a sustained increase in heart rate of at least 30 beats/minute within 10 minutes of standing for age 20 or older, or at least 40 beats/minute for ages 12 to 19, without sustained orthostatic hypotension.
02The paper recommends nonpharmacologic care with 2 to 3 liters of water and 10 to 12 grams of sodium daily, waist-high compression stockings with 30-40 mm Hg pressure, and graduated recumbent exercise at least 30 minutes every other day for 3 months.
03The paper reports high suicide risk in POTS, including 50% of patients at high risk, 15% to 18% reporting past suicide attempts, and 13% reporting another likely attempt, and advises screening for depression, anxiety, and suicidal ideation with appropriate referral.

What it does not show
This is a narrative review, not an original study, so it does not test whether these treatments work. The treatment advice comes from position statements and limited studies, and the paper does not describe how the cited evidence was selected. Medications are off-label for POTS in the US and may worsen fatigue or cause adverse effects. The paper reports high suicide risk but does not provide a validated screening protocol.
The easy way to misread this
Do not read the diagnostic criteria and treatment recommendations as proof that these interventions cure POTS or that medications are FDA-approved for it. The paper says there is no cure, medications are off-label, and evidence is limited.
