Editor's note
A single-patient case report, so this is hypothesis-generating at best. The use of objective measures — a 24-hour heart rate recording and validated symptom questionnaires — strengthens the observation, but with no control there is no way to separate a drug effect from natural recovery over time. The authors, who specialize in dysautonomia, explicitly call for randomized placebo-controlled trials rather than drawing conclusions from one case.
Plain-language abstract
Doctors describe a 42-year-old woman whose fainting episodes and nerve pain, which began after COVID-19 mRNA vaccination, improved substantially on semaglutide — validated symptom scores fell 44-59% and her average heart rate dropped from 97 to 80 bpm.
