How to read results

After a successful reading, you will receive one of the following results on your ECG app. Regardless of the result, if you aren’t feeling well or are experiencing any symptoms, you should talk to your doctor.  

Sinus rhythm

A sinus rhythm result means the heart is beating in a uniform pattern between 50 and 100 BPM. This happens when the upper and lower chambers of the heart are beating in sync. A sinus rhythm result only applies to that particular recording and doesn’t mean your heart beats with a consistent pattern all the time. It also does not mean that you’re healthy. If you’re not feeling well or are feeling any symptoms, you should talk to your doctor.  

Atrial fibrillation

An AFib result means the heart is beating in an irregular pattern between 50 and 120 BPM. AFib is the most common form of serious arrhythmia, or . If you receive an AFib classification and you have not been diagnosed with AFib, you should talk to your doctor.

Low or high heart rate

A heart rate under 50 BPM or over 120 BPM affects the ECG app’s ability to check for AFib, and the recording is considered inconclusive.  

  • A heart rate can be low because of certain medications or if electrical signals are not properly conducted through the heart. Training to be an elite athlete can also lead to a low heart rate. Learn more about low heart rates from the American Heart Association. 
  • A high heart rate could be due to exercise, stress, nervousness, alcohol, dehydration, infection, AFib, or other arrhythmia. Learn more about high heart rates from the American Heart Association.


An inconclusive result means the recording can’t be classified. This can happen for many reasons, such as not resting your arms on a table during a recording, or wearing your Apple Watch too loose. Learn how to .

How to use the ECG app

The ECG app can record your heartbeat and rhythm using  and then check the recording for  (AFib), a form of irregular rhythm.

The ECG app records an electrocardiogram which represents the electrical pulses that make your heart beat. The ECG app checks these pulses to get your heart rate and see if the upper and lower chambers of your heart are in rhythm. If they’re out of rhythm, that could be AFib.

The ECG app is currently available only in certain countries and regions. Learn where the ECG app is available.
