According to a consensus statement from the Heart Rhythm Society, POTS is characterized by frequent symptoms that occur with standing, such as lightheadedness, palpitations, tremor, generalized weakness, blurred vision, exercise intolerance, and fatigue. It is also defined as an increase in heart rate of ≥ 30 beats/min when moving from a recumbent to a standing position (or ≥ 40 beats/min in individuals aged 12-19 years). The absence of orthostatic hypotension (> 20 mm Hg drop in systolic blood pressure) is required. The standing (orthostatic) heart rate of individuals with POTS is often ≥ 120 beats/min.
