The criteria for diagnosis shares many factors with POTS; including the presence of symptoms for 6 months or longer, a Head-Up Tilt Table Test (HUTT) shows tachycardia of 30 BPM or above 120 BPM in the presence of orthostatic intolerance within the first 10 minutes of upright posture. It has other symptoms that are related to the dysfunction of the autonomic system (dysautonomia): problem with temperature regulation, sweat, Cardiac origins of the postural orthostatic tachycardia syndrome.
