my heart rate on my apple watch shows wide fluctuations occasionally even if i am sitting down. It jumps from 65 or 70 to 120 or higher and then comes back down. Is this just a normal read with occasional misreads? does anyone else get this?

Hi

I'm afraid that it is impossible to say whether or not the readings are accurate.

Apple provides the following information regarding heart rate readings and factors that can affect their accuracy:

• Your heart rate. What it means, and where on Apple Watch you’ll find it. - Apple Support

  Note that Apple advises that "Some anomalies may appear in the displayed data, resulting in occasional heart rate measurements that are abnormally high or low".

Whilst keeping in mind that Apple Watch is not a medical device, you may wish to consult your doctor / physician.

Under watchOS 4.x, elevated heart rate notifications are sent when your Apple Watch detects a heart rate that rises over the specified level (on your iPhone, in the Watch app, go to: My Watch > Notifications > Heart Rate) whilst you appear to have been inactive for at least 10 minutes.

If you suspect that your Apple Watch may have identified an abnormal or irregular heart rate, then I would again suggest you consult your doctor / physician, perhaps sharing the readings with them.

Resting heart rate information can be viewed via the Health app on your iPhone (Health Data > Heart > Resting Rate).

Whilst Apple Watch is not a medical device (and, even under ideal conditions, may not be able to record a reliable heart rate reading every time for everyone), heart rate readings have proved helpful to other users, including:

Where do I post a complement to Apple?
