Cardiovascular Autonomic and Immune Mechanism of Post COVID-19 Tachycardia Syndrome
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
• Prior RT-PCR-confirmed COVID-19 infection.
• Post-COVID-19 POTS will be defined as the presence of orthostatic tachycardia (\>30 bpm) and chronic (\>3 months) pre-syncopal symptoms.
