Key Takeaways

  • Apple Watch Low Heart Rate ECGs aren't typically a cause for concern if there's a simple explanation, like if you're sleeping, frequently exercising, or unusually relaxed.
  • If you're not able to find a simple explanation for your heart rate being lower than normal, though, it can be a sign of an infection or abnormal heart rhythm.
  • If you're experiencing symptoms with your Low Heart Rate ECGs, contact your healthcare provider as soon as possible to rule out underlying heart conditions.

Introduction

The Low Heart Rate Apple Watch ECG result is one of the most confusing experiences when monitoring your heart health. In your frustration, you might be wondering, "What does Low Heart Rate mean on my Apple Watch ECG?" Or you might be thinking, "Why does my Apple Watch ECG keep saying Low Heart Rate?" In this guide, we'll help answer these questions and provide clarity on when an Apple Watch Low Heart Rate ECG may be a cause for concern. Let's dive in.

What Does Low Heart Rate Mean on My Apple Watch ECG?

Your Apple Watch ECG provides the following interpretations: Normal Sinus Rhythm, Atrial Fibrillation, Inconclusive, Low Heart Rate, or High Heart Rate. If your heart rate is below 50 beats-per-minute (bpm), your Apple Watch isn't able to interpret your ECG as Normal Sinus Rhythm or Atrial Fibrillation, so it labels your ECG as "Low Heart Rate." If you have ECG version 1, and if your heart rate is above 120 bpm, your Apple Watch labels your ECG as "High Heart Rate." If you have ECG version 2, and if your heart rate is above 150 bpm, your Apple Watch labels your ECG as "High Heart Rate." In both ECG version 1 and ECG version 2, if your heart rate is below 50 bpm, your Apple Watch labels your ECG as "Low Heart Rate." Here's how to check which ECG version you have.

If you're getting Low Heart Rate ECGs on your Apple Watch, it could be because of:

  • Medication that slows your heart down slightly.
  • Being more relaxed than normal.
  • Being in great shape. A lower-than-normal heart rate is often expected in athletes.
  • Sleep 😴. An Apple Watch Low Heart Rate alert while sleeping occurs because sleep naturally lowers your heart rate.

Is Low Heart Rate a Cause for Concern?

If your Apple Watch ECG app shows "Low Heart Rate" for a heart rate between 40 bpm and 50 bpm, there's usually no cause for concern. However, a Low Heart Rate ECG on your Apple Watch may indicate that not enough blood is being pumped out to the rest of your body, which could be a sign of:

  • Sinus Bradycardia.
  • Damage from a previous heart attack.
  • An electrolyte imbalance.
  • Obstructive sleep apnea.
  • An overdose of medication.
  • Not enough potassium or calcium in your blood.
