借助心电图手表进行心电图检测

是的，Withings ScanWatch 系列的心电图手表非常易于使用：只需一个简单的手势，将手指接触手表表壳周围的电极，心电图即可在 30 秒内启动并完成。这些手表提供持续监测和实时提醒，让您随时了解心脏健康状况。心电图记录功能确保您拥有准确的数据，可与医疗服务提供者共享。与临床环境中使用的心电图相似，其准确性极高。

It can tell you whether a 30-second recording looks like atrial fibrillation or like a normal sinus rhythm. It cannot detect a heart attack, and it does not look for other heart conditions. A normal result does not rule those out. If you feel unwell, or if you have chest pain or shortness of breath, contact emergency services rather than taking a reading.

No. The ECG app should not be used with a cardiac pacemaker, an implantable cardioverter-defibrillator, or any other implanted electronic device. The reason is not a safety risk from wearing the watch: an implanted device changes the shape of the ECG trace, so the reading cannot be interpreted reliably. If you have an implant and you have questions about your heart rhythm, your cardiologist and your device check-up are the right route.

Because the signal was not clean enough to classify with confidence, so the algorithm returned no answer rather than risk a wrong one. It usually comes down to contact and stillness: sit down, rest your arm on a table, keep your finger firmly on the metal ring, and stay still for the full thirty seconds. A loose fit or moisture on the wrist can all interrupt the signal.

The recording itself takes place on the watch and it appears in the Withings app either live during the recording if you choose to open your app, or as a final ECG and result in the app after your Bluetooth synchronization. So the short answer is no, you don't need your phone nearby, but you'll need it to open and read the final recording, even if a quick answer will be given on your watch screen.

Yes, you can export and share your ECG as a PDF directly in your Withings App, for free. You can't share an ECG directly through your watch though.

Taking and viewing an ECG does not require a Withings+ subscription. The Cardio Check-Up cardiologist review though is a separate, Withings+ subscription-only feature: you submit a recording you have already taken, a board-certified cardiologist reviews it, and you receive a report in under 24 hours. This feature needs a subscription, but the ECG feature and atrial fibrillation detection are included with your watch without any subscription.

Every recording is saved in the Withings app, where you can look back through them in the ECG results and share any of them with your doctor.

Thirty seconds. You keep a finger on the watch's face and wrap your hand around the metal ring, stay still, and the recording completes on its own. The result appears on the watch, then syncs to the Withings app where you can save it or share it.

心电图手表还具备多种其他功能。您可以在夜间佩戴手表来追踪睡眠，并全天及睡眠后监测心率。运动追踪是 Withings 连接手表的标准功能，整个 ScanWatch 系列均包含此功能。具有更高级"医疗"功能的型号，如 ScanWatch 2 或 Nova，还可追踪体温变化和血氧水平。这些功能对于监测心率过高和潜在心力衰竭症状、维护整体健康至关重要。这类可穿戴设备适合各年龄段人群使用，包括 18 岁及以上的用户。
