Can people with an implanted pacemaker use the heart monitor on the Apple Watch 2?

Hi

Note that the Important safety information in the Apple Watch User Guide presently includes the following information:

Medical device interference Apple Watch contains components and radios that emit electromagnetic fields. Apple Watch, some of the bands, the Apple Watch Magnetic Charging Cable, the Apple Watch Magnetic Charging Case, and the Apple Watch Magnetic Charging Dock contain magnets. These electromagnetic fields and magnets may interfere with pacemakers, defibrillators, or other medical devices. Maintain a safe distance of separation between your medical device and Apple Watch, its bands, the Apple Watch Magnetic Charging Cable, the Apple Watch Magnetic Charging Case, and the Apple Watch Magnetic Charging Dock. Consult your physician and medical device manufacturer for information specific to your medical device. Stop using Apple Watch, its bands, the Apple Watch Magnetic Charging Cable, the Apple Watch Magnetic Charging Case, and the Apple Watch Magnetic Charging Dock if you suspect they are interfering with your pacemaker, defibrillator, or any other medical device.

The watch charger does put out a strong magnetic field, but it is not used while the watch is being worn, and it's possible that it shuts off if the watch is not against it. It would be prudent to keep the charging head away from the pacemaker.

The Wi-Fi and Bluetooth signals are much weaker, and if the pacemaker is affected by them, the wearer would also have to avoid phones, laptops, and wireless keyboards and mice (and stores with anti-theft coils at their doors).

Yes. The watch uses optical sensors to monitor the heart beat. There are no electrical signals that could affect a pacemaker.

You are most welcome! 🙂

As Apple suggests, you may wish to consult your physician and/or pacemaker manufacturer for assistance.
