Understand your ECG test results

Understanding your ECG test result is easy. But for better understanding, we’d recommended consulting a medical expert.

  • Sinus rhythm: Indicates that your heartbeats have a normal, regular pattern. 
  • Inconclusive: An inconclusive result needs further testing to get better answers.
  • Low or high heart rate: A low or high heart rate could indicate a potential heart issue that requires attention.
  • Atrial fibrillation: Atrial fibrillation indicates irregular heartbeat. You should consult a medical expert if you see this.
  • Poor recording: If a poor recording is found, it could be due to movement or poor skin contact with the ECG electrodes. 

The Apple Watch won’t provide you with a thorough report; it will merely summarize your readings. Head over to your iPhone for a detailed analysis.
