Research published has confirmed a link between a Covid infection and a debilitating heart condition called POTS, or postural orthostatic tachycardia syndrome, that has been diagnosed in some patients with long Covid.
The findings, published in the journal Nature Cardiovascular Research, are in line with earlier reports from physicians that Covid may trigger POTS, a disorder of the autonomic nervous system often characterized by a rapid heart rate, low blood pressure, fainting and lightheadedness.
While the researchers found a small but increased risk of POTS following Covid vaccination and, in particular, the first dose, the risk was greater following a Covid infection itself: Getting Covid was linked to a five times greater risk of POTS than vaccination.
