On December 8, in the watchOS 8.3 RC version, the electrocardiogram function that has been pigeon for 3 years was finally launched on the National Bank of China Apple Watch, and today (December 14), the official version of watchOS 8.3 was finally released.
Now, simply upgrade your iPhone (iOS 15.2) and Apple Watch (watchOS 8.3) to the latest version and you can use the Apple Watch EcG.
The specific use of APPSO has been shared in the previous article, but about the Apple Watch test is accurate, in the end how to use this function, I believe you still have a lot of questions. Here, we share some detailed questions about this feature.
In addition to the ECG, arrhythmia notification software is also worth paying attention to
At the same time as the Mobile ECG Atrial Fibrillation PromptIng Software (ECG), there is also a Mobile Pulse Atrial Fibrillation Prompting Software (IRNF). It can be turned on in the "Heart > Arrhythmia Notification Software (IRNF)" in the Health app.
Similar to ecgg function, IRNF is required for users 22 years of age who have never been diagnosed with atrial fibrillation, and when turned on, the Apple Watch will occasionally measure the heart rate to check for arrhythmia symptoms that may be atrial fibrillation. Data is usually performed at rest to ensure accurate readings.
When you receive a room fibrillation notification, it means that apple Watch has identified a heart rhythm that may be atrial fibrillation and has been confirmed by multiple readings. At this time, you should communicate with the doctor to make a diagnosis.
Why can't apple watch SE use the ECG feature?
The ECG records the timing and intensity of the electrical signal when the heart beats, so only the Apple Watch that supports the electrode-type heart rate sensor can detect the electrical signal, and the Apple Watch SE, although released last year, does not have an electrode-type heart rate sensor.
How well does the Apple Watch test compare to a 12-lead ECG in a hospital?
A 12-lead ECG records electrical signals from different angles of the heart, generating 12 different waveforms. The Apple Watch can only measure a waveform similar to one of the 12 different waveforms, so the results are naturally better than professional detection.
A single-lead ECG provides information about heart rate and rhythm and classifies atrial fibrillation. Portability without medical advice and on-the-go detection are its greatest advantages.
Is the ECG data detected by the Apple Watch accurate?
Of course, in actual use, the software may detect more records that are considered indeterminate and unclassifiable.
▲For example, the results of the test with two hands.
How can I use apple watch to focus on family rhythm problems?
If you set up an Apple Watch for your family, you can also see the IRNF prompt on your phone, and your family can also share information about the ECG with you.
The ECG software launched by BNC is "version 1", so when will the "version 2" that has been updated overseas be launched?
Software version 1 can tell whether atrial fibrillation is present in the heart rate range of 50 to 120 beats per minute, while software version 2 can distinguish whether atrial fibrillation is present in the heart rate range of 50 to 150 beats per minute.
The relevant domestic institutions have previously reviewed software version 1, so Apple Watch has not yet launched version 2 updates. Apple has a new version ready, and after the relevant departments approve it, it will be synced to our Apple Watch.
▲ EcG above 120 heart rate can not be used to check for atrial fibrillation.
How should we use this feature?
First of all, we must make it clear that the electrocardiogram measured by apple watch cannot be used as a test for diseases such as heart disease, it gives us tips and references.
When you're feeling fast beats, fatigue, or other heart discomfort, or you're not feeling well but you're alerted to Apple Watch atrial fibrillation, open the Mobile ECG Atrial Fibrillation Reminder Software to take a record. Although this result is not as accurate as professional instruments, it is enough to be an important reference for doctors when diagnosing you.
As mentioned in the previous article, although the test results of this function may not be recognized by medical institutions, whether it is the "Mobile Pulse Atrial Fibrillation Prompt Software" that reminds us of possible symptoms of atrial fibrillation, or the "Mobile ECG Atrial Fibrillation Prompt Software" that can draw a single-lead ECG, it is a step for us to take in personal health management.
