Orthostatic tachycardia (OT) affects some patients after concussion/mild traumatic brain injury (mTBI). In this study, we sought to identify the factors associated with increased risk for OT in patients with mTBI. We conducted a retrospective review of 268 patients (8-25 years) with mTBI/concussion to determine the prevalence of OT, defined as orthostatic heart rate change ≥40 bpm for those ≤19 years of age and ≥30 bpm on active standing test for those >19 years of age. Among the study population, 7% (n = 19) exhibited post-concussive OT. The only significant difference between OT and non-OT groups was that history of prior concussion was more prevalent in the OT group. A substantial subset (7%) of concussion clinic patients exhibit OT. While POTS literature describes female and adolescent predominance, post-concussive OT had similar prevalence across age and gender groups in this study, suggesting that it may be distinct from POTS.
直立性心动过速（OT）会影响一些脑震荡/轻度创伤性脑损伤（mTBI）后的患者。在本研究中，我们试图确定与mTBI患者OT风险增加相关的因素。我们对268例年龄在8至25岁之间的mTBI/脑震荡患者进行了回顾性研究，以确定OT的患病率，OT定义为19岁及以下患者直立性心率变化≥40次/分钟，19岁以上患者主动站立测试时心率变化≥30次/分钟。在研究人群中，7%（n = 19）表现出脑震荡后OT。OT组和非OT组之间唯一的显著差异是既往脑震荡史在OT组中更为普遍。相当一部分（7%）脑震荡门诊患者表现出OT。虽然体位性心动过速综合征（POTS）的文献描述了女性和青少年占主导，但在本研究中，脑震荡后OT在各年龄和性别组中的患病率相似，这表明它可能与POTS不同。
