Summary

This trial tests a device that sends mild electrical signals to the ear to help people with long-term symptoms after COVID-19. It focuses on those who have ongoing issues like a fast heartbeat and dizziness. The device aims to reduce inflammation and improve these symptoms by stimulating a nerve that helps control these functions.

Who is the study for?
This trial is for individuals who previously had COVID-19 and now suffer from a condition called post-COVID-19 POTS, characterized by rapid heartbeat when standing up and symptoms like dizziness lasting over 3 months. It's not for those with heart disease, on certain medications like steroids or biologics, post-menopausal women, pregnant or breastfeeding people, those with liver issues, seizure history, recent cardiovascular procedures, substance abuse problems, severe mental conditions, stroke history or impaired kidney function.
What is being tested?
The study investigates the role of inflammation in long-term rapid heartbeat after COVID-19 (post-COVID-19 POTS). Researchers are measuring levels of an inflammatory marker (IL-6) and examining the effects of chronic stimulation of the parasympathetic nervous system to reduce inflammation in affected patients compared to healthy controls.
What are the potential side effects?
Since this trial focuses on monitoring biological markers rather than testing new drugs or therapies directly administered to participants there may be minimal side effects related specifically to the interventions being studied.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Effect of OI symptoms & inflmmation after Restoring PNS functions in post-COVID POTS patients.Experimental Treatment1 Intervention
Effects of restoring PNS function in post-COVID-19 POTS patients with chronic transcutaneous vagus nerve stimulation (tVNS) on inflammation, orthostatic tachycardia and OI symptoms.The subjects with POTS will be randomized, where TENS 7000 device will be placed to active and sham location.Autonomic symptoms assessment questionnaire (COMPASS-31),32 quality of life EQ-5D and neuropsychological tests
Group II: Compare inflammatory markers (IL-6) in post- COVID 19 POTS patients with ControlsExperimental Treatment2 Interventions
Biochemical endpoints: Measurement of Inflammatory markers (especially IL-6) in both Post- COVID-19 POTS patients and compare it with controls. Controls are the participants who recovered from COVID 19 infection with no sequelae

Mechanism Of Action

Other Research
Common treatments for Post-COVID Syndrome, particularly those addressing chronic tachycardia and orthostatic intolerance, often focus on regulating heart rate and improving autonomic function. Ivabradine, for example, works by inhibiting the If current in the sinoatrial node, effectively reducing heart rate without affecting blood pressure. This is crucial for Post-COVID Syndrome patients who experience persistent tachycardia, as it helps manage heart rate and reduce symptoms like fatigue and dizziness. Other treatments may include beta-blockers, which also reduce heart rate and improve symptoms of orthostatic intolerance by blocking the effects of adrenaline on the heart. These mechanisms are important because they directly address the dysregulated autonomic responses seen in many Post-COVID Syndrome patients, thereby improving their quality of life.
