Postural orthostatic tachycardia syndrome is the most frequent cardiovascular autonomic disorder following COVID-19 infection or vaccination.

ABSTRACT:

Background

Cardiovascular autonomic disorders (CAD) were described following COVID-19 infection and vaccination, but previous reports were limited in size and follow-up.
