Smartwatch allows easy detection of arrhythmia. Such an approach is widely used for detecting atrial fibrillation. However, there has been no consensus on the diagnostic power of smartwatch-detected supraventricular tachycardia (SVT). We reported three patients of SVT presenting with infrequent palpitations. Their SVTs were not documented with single-lead or standard ECG in hospital before, but only recorded by the single-lead ECG on smartwatches. Electrophysiological studies confirmed the mechanisms of these SVTs and led to successful catheter ablations. In conclusion, in patients with recurrent symptomatic tachycardia and a smartwatch-detected SVT, an electrophysiological study is indicated rather than to wait for a standard ECG for clinical decision. This approach might prevent the delay for successful treatment.

使用智能手表检测室上性心动过速有助于导管消融的决策：一个案例系列

Smartwatch 可以轻松检测心律失常。这种方法被广泛用于检测心房颤动。然而，对于智能手表检测到的室上性心动过速 (SVT) 的诊断能力尚未达成共识。我们报告了 3 名 SVT 患者出现不常见的心悸。他们的 SVT 之前没有在医院用单导联或标准 ECG 记录，而只是通过智能手表上的单导联 ECG 记录。电生理学研究证实了这些 SVT 的机制并导致成功的导管消融。总之，对于复发性症状性心动过速和智能手表检测到 SVT 的患者，需要进行电生理研究，而不是等待标准 ECG 做出临床决定。这种方法可能会阻止成功治疗的延误。
