Concentration of autoantibodies against muscarinic cholinergic receptors in patients with postural orthostatic tachycardia syndrome. The mean concentration of muscarinic acetylcholine receptor autoantibodies was lower than the cut‐off value, except for the M4 subtype with a mean of 11.0±9.3 units/mL. Some patients had autoantibodies against all 5 receptor subtypes that exceeded the maximum cut‐off value. Three patients had mAChR M1 antibody values that exceed the chart, 5 patients had antibodies >40 units/mL for mAChR M2, and 4 patients each had antibodies against mAChR M3, M4, and M5 >40 units/mL; these patient values are graphed in Figure 4.
