[34] POTS has also been divided into several types (see § Causes), which may benefit from distinct treatments. [77] People with neuropathic POTS show a loss of sweating in the feet during sweat tests, as well as impaired norepinephrine release in the leg, [78] but not arm. [1] [77] [79] This is believed to reflect peripheral sympathetic denervation in the lower limbs. [78] [80] [1] People with hyperadrenergic POTS show a marked increase of blood pressure and norepinephrine levels when standing, and are more likely to have from prominent palpitations, anxiety, and tachycardia.

An increase in heart rate upon moving to an upright posture is known as orthostatic (upright) tachycardia (fast heart rate). It occurs without any coinciding drop in blood pressure, as that would indicate orthostatic hypotension. [29] Certain medications to treat POTS may cause orthostatic hypotension. It is accompanied by other features of orthostatic intolerance—symptoms that develop in an upright position and are relieved by reclining. [29] These orthostatic symptoms include palpitations, light-headedness, chest discomfort, shortness of breath, [29] nausea, weakness or "heaviness" in the lower legs, blurred vision, and cognitive difficulties. [1] Differential diagnoses [ edit ]

Aggravating factors include exertion (81%), continued standing (80%), heat (79%), and after meals (42%).

In adults, the primary manifestation is an increase in heart rate of more than 30 beats per minute within ten minutes of standing up. [1] [29] The resulting heart rate is typically more than 120 beats per minute. [1] For people between ages 12 and 19, the minimum increase for a POTS diagnosis is 40 beats per minute. [30] POTS is often accompanied by common features of orthostatic intolerance—in which symptoms that develop while upright are relieved by reclining. [29] These orthostatic symptoms include palpitations, light-headedness, chest discomfort, shortness of breath, [29] nausea, weakness or "heaviness" in the lower legs, blurred vision, and cognitive difficulties. [1] Symptoms may be exacerbated with prolonged sitting, prolonged standing, alcohol, heat, exercise, or eating a large meal. [ citation needed]
