This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Some people develop long-lasting symptoms after COVID-19, including a rapid heartbeat, dizziness, and fatigue that can last for months. This study is investigating why this happens by looking at how the nervous system and immune system work together after COVID-19. Researchers will also test whether a non-invasive device called transcutaneous vagus nerve stimulation (tVNS)—which gently stimulates a nerve in your neck using electrical pulses—can reduce inflammation and improve these symptoms.
Doctors have noticed that people with post-COVID rapid heartbeat syndrome have changes in how their nervous system controls inflammation. By understanding this connection, researchers hope to find new ways to help patients recover and reduce their debilitating symptoms.

You will have blood drawn to measure inflammation markers and answer questions about your symptoms. If you have post-COVID rapid heartbeat syndrome, you may be randomly assigned to wear a small electrical stimulation device on your neck for several weeks—either at the active setting or a sham (inactive) setting. Throughout the study, you will complete questionnaires about how you feel, your quality of life, and any changes in your symptoms.
