What You Need to Know Before You Apply

What is the purpose of this trial?

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.

Will I have to stop taking my current medications?

The trial requires that participants do not use certain medications, such as chronic steroids, NSAIDs (non-steroidal anti-inflammatory drugs), and biologics like anti-IL6 and anti-TNF-alpha drugs. If you are taking these, you may need to stop before joining the trial.

Is the treatment for post-COVID-19 tachycardia syndrome safe for humans?

The studies reviewed focus on understanding heart rate variability and autonomic nervous system function in post-COVID-19 patients, but they do not provide specific safety data for a treatment. They suggest that the effects of COVID-19 on heart function may decrease over time, but no direct safety information about a treatment is available.12345

How does the treatment for post-COVID-19 tachycardia syndrome differ from other treatments?

The treatment for post-COVID-19 tachycardia syndrome is unique because it focuses on addressing autonomic dysfunction, which is a key factor in this condition. Unlike standard treatments, it may involve a combination of lifestyle changes, heart rate-lowering medications like ivabradine or β-blockers, and supportive measures such as compression stockings and increased salt and fluid intake. This approach is tailored to manage the specific symptoms and underlying mechanisms associated with post-COVID-19 autonomic dysfunction.13678

What data supports the effectiveness of this treatment for post-COVID-19 tachycardia syndrome?

The research suggests that post-COVID-19 patients with symptoms like tachycardia (fast heart rate) and orthostatic intolerance (difficulty standing up without feeling dizzy) may benefit from treatments that include heart rate-lowering medications and lifestyle changes, such as increasing salt and fluid intake. These approaches have shown potential in managing similar symptoms in non-COVID-related conditions.13679

Are You a Good Fit for This Trial?

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.

Inclusion Criteria

I have had a fast heart rate and near-fainting for over 3 months after COVID-19.
I have had a fast heart rate and near-fainting for over 3 months after COVID-19.

What Are the Treatments Tested in This Trial?

Interventions

  • Autonomic Symptoms assessment
  • Determine the inflammatory and immune profile of post-COVID-19 POTS patients
  • Measurement of PNS activity by HRV (Heart rate Variation)
Trial Overview 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.
How Is the Trial Designed?
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

Published Research Related to This Trial

In a study of 20 patients with new-onset postural orthostatic tachycardia syndrome (POTS) and other autonomic disorders following COVID-19, 85% experienced ongoing symptoms 6 to 8 months after infection, highlighting the long-term impact of the virus on autonomic function.
Most patients required both non-pharmacologic and pharmacologic treatments, indicating that comprehensive management strategies are essential for addressing autonomic dysfunction after COVID-19.
Postural orthostatic tachycardia syndrome (POTS) and other autonomic disorders after COVID-19 infection: a case series of 20 patients.Blitshteyn, S., Whitelaw, S.[2021]
A study of 14 patients revealed that some individuals who had COVID-19 developed postural tachycardia syndrome (PoTS), showing symptoms similar to those seen in non-COVID-related PoTS cases.
The authors suggest using an active stand test for patients with cardiovascular symptoms after COVID-19 and recommend training for clinicians to manage the expected rise in PoTS cases linked to the pandemic.
Observational case series of postural tachycardia syndrome (PoTS) in post-COVID-19 patients.Gall, NP., James, S., Kavi, L.[2022]
Patients with Post-COVID-19 syndrome (PCS) exhibited significant autonomic dysfunction characterized by increased heart rate and reduced heart rate variability (HRV) parameters, indicating a sympathetic predominance compared to control subjects.
After 6 months, PCS patients showed improvements in HRV and arterial pressure variability, suggesting that the negative effects of COVID-19 on autonomic control may diminish over time, as their responses during the head-up tilt test became similar to those of healthy individuals.
