Parasitescan transmit diseases, such as Chagas, that can cause POTS symptoms. Some patients report developing POTS after having Lyme disease. Porphyriashave been associated with POTS symptoms (Stewart & Hensley, 1981). Porphyrias are rare, mainly genetic disorders that affect the body's ability to make hemoglobin. They are caused by deficiencies in enzymes involved in the synthesis of heme.
The hallmark symptom of POTS is an increase in heart rate by at least 30 beats per minute within 10 minutes of assuming an upright position. For people aged between 12 and 19, the minimum increase for diagnosis is 40 beats per minute. This symptom is known as orthostatic (upright) tachycardia (fast heart rate).
