Postural Tachycardia Syndrome (PoTS) is a common symptom of long COVID and in this condition, simply standing up makes your heart race. Your heartbeat can speed up by at least 30 beats per minute after you move from sitting or lying down to standing. This may not happen immediately and feel dizzy even 10 minutes after moving from sitting to standing. It can be challenging for the affected people as their body is unable to adjust to gravity.
PoTS happens when your body’s autonomic nervous system fails to control your blood pressure levels and your heart rate to make up for the change in posture.
