Graves’ disease is the most common form of hyperthyroidism in the pediatric population. While the most prevalent symptoms seen in children with Graves’ disease include goiter and excessive sweating (Minamitani et al., 2017), diagnosis is frequently delayed due to presentation with non-specific symptoms (Léger et al., 2018). This case report is of a 12-year-old female who presented to her pediatrician with a one month history of episodes of tachycardia both with physical exertion and at rest. Notably, these episodes were discovered on her electronic smartwatch by its heart rate monitoring feature. Further pertinent positives elicited in the patient's review of systems included increasing anxiety, diaphoresis, intermittent hand tremors, and recent weight loss. These findings led to further workup that included thyroid studies, culminating in a diagnosis of Graves’ disease. Indeed, this patient's smartwatch aided in her initial presentation to her physician and allowed for prompt workup and diagnosis. There exist limited studies to date on the use of smartwatches to detect cardiac-related conditions in children, which may be due to the absence of Food and Drug Administration approval for certain cardiac-related smartwatch features in this patient population.

格雷夫斯病是儿科人群中最常见的甲状腺功能亢进症。虽然格雷夫斯病儿童最常见的症状包括甲状腺肿和出汗过多（Minamitani 等人，2017 年），但由于出现非特异性症状，诊断经常被延迟（Léger 等人，2018 年）。本病例报告是一名 12 岁的女性，她向儿科医生提出了一个月的心动过速发作史，包括体力消耗和休息时。值得注意的是，这些事件是在她的电子智能手表上通过心率监测功能发现的。在患者对系统的回顾中引发的其他相关积极因素包括焦虑增加、出汗、间歇性手部震颤和近期体重减轻。这些发现导致了包括甲状腺研究在内的进一步检查，最终诊断为格雷夫斯病。事实上，这名患者的智能手表有助于她向医生进行初步介绍，并允许及时进行检查和诊断。迄今为止，关于使用智能手表检测儿童心脏相关疾病的研究有限，这可能是由于食品和药物管理局未批准该患者群体中某些与心脏相关的智能手表功能。
