Summary
The term post-acute COVID-19 syndrome or Long COVID is a disabling syndrome that persists beyond the 3-month convalescence period after COVID-19 infections. This syndrome affects mostly women (\~80%), present with chronic tachycardia and Orthostatic intolerance symptoms without any identifiable cause. In addition, non-specific symptoms such as fatigue, headache, and "brain fog", commonly described in POTS patients are also present in this novel condition, recently named post-COVID-19 tachycardia syndrome, POTS variant. Reduced Vagal activity and unresolved inflammation is post-COVID-19 POTS is hypothesized as the cause of Long COVID

Interventions
Inflammatory and immune profile of post-COVID-19 POTS patients. Reduced PNS activity (vagal tone) in relation to persistent inflammation.
Inflammatory and immune profile of healthy controls. Controls are the subjects who recovered from COVID-19 infection with no sequelae.
Inflammatory biomarkers after restoring PNS function in post-COVID-19 POTS patients, by chronic transcutaneous vagus nerve stimulation (tVNS) in post COVID-19 POTS patients
