If you’re looking for an easy way to keep track of your heart health, look no further than the Apple Watch 3. With its built-in sensors and features, it’s one of the most accurate and reliable ways to monitor your heartbeat and make sure you stay healthy.

Can the Apple Watch 3 Detect Heart Palpitations?

Yes, the Apple Watch 3 (and later series) can detect heart palpitations. The watch uses an infrared sensor and photoplethysmograph (PPG) to measure pulse rate and detect irregularities in your heartbeat which may suggest atrial fibrillation (AFib). When an irregular rhythm is detected, the watch will provide a notification to the user. However, it’s important to note that this technology is not intended to be used as a diagnosis and should not replace monitoring by a qualified healthcare professional.

You can then turn this feature on or off.

Does the Apple Watch 3 Have ECG Detection Capabilities?

Activating a Heart Rate Watch

To activate your heart rate watch, first press the digital crown on the side of your watch. This will bring up your apps. Look for the Heart app, which features a red background with a heart on it. Tap the Heart app to begin your heart rate reading. Additionally, you can scroll down to view your resting heart rate and walking average heart rate.

Troubleshooting an Apple Watch Not Displaying Heart Rate

It could be that the heart rate monitoring feature on your Apple Watch is not enabled. To ensure that it is, open the Watch app on your iPhone and go to My Watch > Privacy > Motion & Fitness. Make sure that both “Fitness Tracking” and “Heart Rate” are enabled. It’s also possible that you have Workout Power Saving Mode enabled in the My Watch > General menu; if so, try turning it off and seeing if that helps.

Troubleshooting Apple Watch Heart Rate Detection Issues

It is possible that the Apple Watch may not be able to detect your heart rate if the heart rate monitor is not functioning properly. If this is the case, you may need to restart or reset your device by pressing and holding the Side button until the power off slider bar appears, then sliding it to turn off Apple Watch. Press and hold the Side button again until the Apple Watch logo appears. Additionally, you should make sure that your skin is clean and dry when you wear your Apple Watch as sweat, lotions, and oils can interfere with its sensors.

Accuracy of Apple Watch for Measuring Heartbeat

The Apple Watch is generally accurate for measuring heart rate, but not as accurate as a dedicated medical device. To get the most accurate readings from the Apple Watch, it’s important to wear it securely and snugly on your wrist. Additionally, avoid using it when you’re exercising vigorously or when your body temperature is elevated, as this can affect its accuracy. Finally, calibration may be needed after a software update or when swapping out bands. If you need an extremely reliable reading of your heart rate, you may want to invest in an ECG monitor or other dedicated medical device.


The Apple Watch Series 3 is a powerful smartwatch that offers a wide range of features, including the ability to track your fitness and health goals, stay connected with your loved ones, and even detect possible irregular heart rhythms. With its built-in IRNF feature, it can give you notifications when it detects an episode of irregular heart rhythm suggestive of atrial fibrillation (AFib), making it a great tool for monitoring your heart health. Furthermore, it also allows you to customize the watch face with various complications that can provide easy access to important information. All in all, the Apple Watch Series 3 is an excellent device for anyone looking for a comprehensive health and fitness tracking system.
