The association between dysautonomia and long-COVID syndrome has gained considerable interest. This study retrospectively characterized the findings of autonomic reflex screen (ARS) in long-COVID patients presenting with orthostatic intolerance (OI). Fourteen patients were identified. All patients had normal cardiovagal function and 2 patients had abnormal sudomotor function. The head-up tilt table (HUTT) was significantly abnormal in 3 patients showing postural orthostatic tachycardia syndrome (POTS). CASS ranged from 0 to 2. The most common clinical scenario was symptoms of orthostatic intolerance without demonstrable HUTT orthostatic tachycardia or orthostatic hypotension (OH) (n = 8, 57 %). In our case series, most long-COVID patients presenting to our laboratory with OI had no significant HUTT abnormalities; only 3 patients met the criteria for POTS.
自主神经功能障碍与长新冠综合征之间的关联引起了相当大的关注。本研究回顾性分析了表现为直立不耐受（OI）的长新冠患者自主反射检查（ARS）的结果。共确定了 14 名患者。所有患者的心迷走神经功能正常，2 名患者的自主神经汗腺功能异常。3 名患者的直立倾斜试验（HUTT）明显异常，表现为体位性心动过速综合征（POTS）。CASS 范围为 0 至 2。最常见的临床情况是直立不耐受症状，但 HUTT 直立性心动过速或直立性低血压（OH）无明显异常（n=8，57%）。在我们的病例系列中，大多数因 OI 就诊于我们实验室的长新冠患者的 HUTT 异常不明显；只有 3 名患者符合 POTS 的标准。
