This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This research is studying a problem that affects some people who had COVID-19: they develop a rapid heartbeat and feel dizzy, especially when standing up. The study is investigating whether these symptoms are caused by changes in how the body's nervous system controls inflammation. The researchers will test whether a device called transcutaneous vagus nerve stimulation (tVNS) — which gently stimulates a nerve in your neck — can help reduce inflammation and improve your symptoms.
Many people who had COVID-19, even mild cases, develop long-lasting symptoms like rapid heartbeat, chest pain, and dizziness. Current treatments don't work well for everyone. This trial exists to understand the underlying cause — specifically, whether reduced nerve function leads to persistent inflammation — and to see if stimulating the vagus nerve can restore the body's natural anti-inflammatory system.
If you join this study, you will be divided into two groups. One group will wear a small device (TENS unit) on the neck that delivers gentle nerve stimulation, while the other group will wear a device that looks the same but doesn't deliver active stimulation. You will have blood tests to measure inflammation markers, complete questionnaires about your symptoms and quality of life, and possibly have other assessments. The study will track how your symptoms change over time while using the device.
