How to interpret the results of an Apple Watch electrocardiogram
When you perform the ECG, You will receive a notification on your iPhone with a report on the electrocardiogram. You can also access all the ECGs you have taken from the Health app > Explore > Heart. The report may give different results depending on your needs. Apple explains very well on its website:
- Sinus rhythm: Indicates that the heart beats evenly between 50 and 100 beats per minute (BPM), with the atria and ventricles in synchrony.
- Atrial fibrillation (AF): This indicates an irregular heart rhythm and is the most common serious arrhythmia. If you have not been diagnosed with AF and get this result, you should see a doctor.
- High or low heart rate: If the heart rate is too high or too low, the test may fail. ECG app version 1 has difficulty detecting AF at rates below 50 BPM or above 120 BPM, while version 2 has problems with rates outside the range of 50 to 150 BPM.
- Inconclusive: An inconclusive result indicates that the record cannot be evaluated.
