摘要
目的：心房颤动（AF）是心脏瓣膜手术后常见的早期心律失常，会限制体力活动。我们旨在评估 Apple Watch Series 5 单导联心电图（ECG）检测心脏瓣膜手术后患者房颤的标准有效性：我们从挪威北部大学医院招募了 105 名患者，其中 93 人完成了研究。所有患者在术后第二天至第三天或第三天至第四天每天三次或三次以上使用智能手表进行单导联心电图检查。这些结果与连续 2-4 天的心电图遥测监测和术后第三天的 12 导联心电图进行了比较：结果：将 Apple Watch 心电图与心电图监测进行比较，发现房颤的敏感性和特异性分别为 91% (75, 100) 和 96% (91, 99)。准确率为 95% (91, 99)。将 Apple Watch 心电图与 12 导联心电图进行比较，灵敏度为 71%（62, 100），特异性为 92%（92, 100）：结论：苹果智能手表单导联心电图具有较高的灵敏度和特异性，可作为检测心脏瓣膜手术后患者房颤的有用工具。
Validity of a smartwatch for detecting atrial fibrillation in patients after heart valve surgery: a prospective observational study.
Objectives: Atrial fibrillation (AF) is a common early arrhythmia after heart valve surgery that limits physical activity. We aimed to evaluate the criterion validity of the Apple Watch Series 5 single-lead electrocardiogram (ECG) for detecting AF in patients after heart valve surgery.
Design: We enrolled 105 patients from the University Hospital of North Norway, of whom 93 completed the study. All patients underwent single-lead ECG using the smartwatch three times or more daily on the second to third or third to fourth postoperative day. These results were compared with continuous 2-4 days ECG telemetry monitoring and a 12-lead ECG on the third postoperative day.
Results: On comparing the Apple Watch ECGs with the ECG monitoring, the sensitivity and specificity to detect AF were 91% (75, 100) and 96% (91, 99), respectively. The accuracy was 95% (91, 99). On comparing Apple Watch ECG with a 12-lead ECG, the sensitivity was 71% (62, 100) and the specificity was 92% (92, 100).
Conclusion: The Apple smartwatch single-lead ECG has high sensitivity and specificity, and might be a useful tool for detecting AF in patients after heart valve surgery.
