ECG Findings

The findings are categorized into the following.

  • Sinus rhythm
  • Atrial fibrillation
  • Low or high heart rate
  • Inconclusive

Let’s check what each of them mean and does it signal anything worrying!

Sinus Rhythm

Sinus rhythm results indicate that the heart is beating in a uniform pattern (50 - 100 BPM) and the upper-lower chambers of the heart are in complete sync. Still, if you're experiencing any discomfort, it’s better to consult a health expert or a physician

Atrial fibrillation

This rhythm means your heart is experiencing some chaotic electrical signals. It also signals an irregular and often rapid heart rate. It is the most common form of serious arrhythmia (heart beating too fast or too slowly).

Low or High heart rate

When your heart rate is somewhere between 50 BPM or over 120 BPM, it affects the ECG apps ability to find anything conclusive. As such, the recording is considered as inconclusive.


The Apple Watch ECG inconclusive recording is self-explanatory. It does not lead to any sort of firm conclusion or result.
