Frequently Asked Questions

Why is ECG not available on my Apple Watch?
ECG may be unavailable due to regional restrictions, incompatible watch model (needs Series 4 or later), outdated software, or incomplete setup in the Health app. The feature is only available in certain countries due to medical device regulations.
Which Apple Watch models support ECG?
ECG is supported on Apple Watch Series 4, 5, 6, 7, 8, 9, SE (2nd generation), and Ultra models. Earlier models like Series 1, 2, 3, and original Apple Watch do not have the necessary hardware for ECG functionality.
Can I use ECG if I'm under 22 years old?
No, Apple's ECG app requires users to be 22 years or older. This age restriction is built into the app and cannot be bypassed, as it's part of the FDA clearance requirements for the medical device feature.
What countries support Apple Watch ECG?
ECG is available in the US, most European Union countries, UK, Canada, Australia, Japan, South Korea, and several other regions. The feature continues to expand to new countries as Apple receives regulatory approval from local health authorities.
Do I need cellular Apple Watch for ECG?
No, cellular connectivity is not required for ECG. The feature works on both GPS and GPS + Cellular Apple Watch models. You only need the watch to be paired with a compatible iPhone that has the Health app set up.
