Make an ECG using the ECG app on the Apple Watch 6

What is an ECG

An electrocardiogram (also known as ECG or an ECG (also known as EKG) is an examination that measures the frequency and timing of electrical signals that trigger the heart beat.

The ECG app can record an electrocardiogram that reflects the electrical pulses that cause the heartbeat. The ECG app monitors these electrical pulses to determine your heart rate and determine whether the upper and lower chambers in your heart are both in sync.

Sinus rhythm

A sinus rhythm results means that the heart beats in a consistent pattern of 50 to 100 BPM. This occurs when the lower and upper chambers within the heart are in harmony. The sinus rhythm results is only applicable to the specific recording, and does not mean that your heart beats in regularity every day. It doesn’t suggest that you’re in good health. If you’re feeling unwell or have any signs it is best to talk to your physician.

Atrial fibrillation

A AFib result indicates that the heart beats in an irregular rhythm. AFib can be described as the most frequent form of serious arrhythmia or irregular heartbeat. If you are given an AFib diagnosis and haven’t been diagnosed with AFib then you must consult your physician. The ECG app version. 1 will determine if an AFib is present Between 50-120 BPM. The ECG application version. 2 will test for AFib between 50-150 BPM.

Find out the details about ECG app versions available and discover what version you’re using.

Heart rate that is high or low

A heart rate of less than 50 BPM or above 120 BPM in ECG version 1 can affect the ECG app’s ability to look for AFib. In ECG version 2.2 the heart rate of a person who is less than 50 BPM or greater than 150 BPM can impact the ECG application’s ability to test for AFib.

  • Heart rate can be low due to certain medications, or because electrical signals aren’t being correctly transmitted via the heart. Training to become an elite athlete may cause a decrease in heart rate.
  • A heart rate that is high may be caused by tension, exercise, nervousness, stress drinking, dehydration, alcohol AFib, infection or another arrhythmia.


A non-conclusive outcome means that the audio file isn’t categorized. This could be due to any of these circumstances:

  • In ECG version 1 your heart rate falls between 100 to 120 BPM and you’re not suffering from AFib. It is ECG software version 2 also was evaluated in a clinical study of 546 people and showed 99.3 percent accuracy with regard to the classification of sinus rhythms, and 98.5 percent sensitivity for AFib classification for classification results.
  • You are using a pacemaker or an implantable cardioverter (ICD).
  • The recordings may reveal symptoms of arrhythmias in other forms or heart problems that the app was not intended to detect.
  • Certain physical conditions can stop a tiny percentage of users from producing enough signals to create an excellent recording.
