Jan 25, 2016 · Beta-adrenergic blockers are commonly used in cardiology clinics to control tachycardia, but tolerance can be a problem in many patients with POTS. While reducing the HR in POTS would be useful if the tachycardia was "over-compensation" for a physiological stimuli (i.e., a truly hyperdynamic circulation), but could be counter-productive if the ...

Beta-blockers are especially recommended in hyperadrenergic subtype associated with sinus tachycardia > 120 bpm on standing (Fedorowski 2018). Beta blockers decrease heart rate, force of contraction, and conduction velocity through the heart.

Indications: low-dose beta-blockers are especially recommended in POTS patients with ‘hyperadrenergic’ subtype associated with sinus tachycardia >120 bpm on standing. Contraindications: Beta-blockers may aggravate orthostatic intolerance in low-BP phenotype, asthma and paroxysmal chest pain.

Aug 11, 2024 · Currently, no medications have been approved by the FDA to treat POTS. However, several medicines can be prescribed off-label when needed. Your doctor might suggest one or more of these: fludrocortisone (helps the kidneys retain sodium) midodrine (causes the blood vessels to tighten) beta blockers (slow down the heart rate)

Beta blockers, mainly propranolol, are used fairly frequently in POTS. Basically beta-blockers are a drug that primarily reduces heart rate. It has been shown that propranolol may be helpful in reducing heart rate and improving symptoms in POTS patients.

Mar 1, 2018 · Beta blockers are one of the most popular and first-prescribed treatments for postural orthostatic tachycardia syndrome (POTS) because they help treat tachycardia by lowering heart rate. But how exactly do they work?

All in all, we concluded that β-blockers are effective in treating POTS in children and adolescents, alleviating orthostatic intolerance, and improving hemodynamic abnormalities. Postural tachycardia is the main hemodynamic feature of POTS children.

Beta blockers have been reported to be a useful treatment for POTS patients with beta-receptor super-sensitivity, high noradrenaline levels and/or hyper-adrenergic states. However, β-blockers may exacerbate hypotension and reduce renin levels.

Aug 17, 2009 · Given the conflicting data on the effectiveness of β-blockers in POTS, we conducted a short-term single-blind crossover trial to test the hypothesis that low-dose propranolol would reduce orthostatic tachycardia and improve upright symptoms in patients with POTS.

PoTS is an abnormal increase in heart rate that occurs on sitting up or standing, and symptoms include dizziness, fainting, palpitations, chest pain and shortness of breath, among others (NHS, 2019).
