Tragus Stimulation for POTS Treatment

"Transcutaneous auricular vagus nerve stimulation (tVNS) is an emerging therapeutic modality in cardiovascular diseases. tVNS has been shown to exert antiadrenergic and anti-inflammatory effects in humans. Recently, tVNS has been tested in experimental and human POTS, leading to improved autonomic function, reduction of anti-autonomic autoantibodies and inflammatory cytokines.~Parasym device; Parasym Health, London, United Kingdom Frequency: 20Hz, pulse width: 200μs, amplitude will be individually titrated to 1 mA below the level that caused mild discomfort."
