According to a study published Monday in Nature Cardiovascular Research, COVID-19 and mRNA COVID-19 vaccines are linked to postural orthostatic tachycardia syndrome (POTS), a debilitating autonomic nervous system disorder.

POTS symptoms include an elevated heart rate, dizziness, heart palpitations, fainting, lightheadedness, headaches, chest pain, brain fog, anxiety, depression and fatigue, among others.

Comparing POTS diagnoses 90 days prior to and following vaccine exposure, investigators found that some patients vaccinated against COVID-19 may develop POTS as a response to the shot.

They also found that people diagnosed with COVID-19 are five times more likely to develop POTS after infection than those who developed it after vaccination.
