Importantly, POTS is not associated with mortality, with many patients improving to some degree over time after diagnosis and proper treatment. As patients transition from a prone to upright position on the table, those with POTS experience dramatic increases in heart rate. Postural tachycardia syndrome (PoTS) is an abnormal increase in heart rate that occurs after sitting up or standing.
