- Tell-tale signs of Sinus Rhythm include a regular heart rhythm, a heart rate between 60 and 100 beats-per-minute, normal P waves, a normal PR interval, and a normal QRS complex.
- Sinus Rhythm is the rhythm of a healthy heart and isn't a cause for concern.
- If you're in Sinus Rhythm, you're staying heart healthy.
Hello, heart hero. In your quest to identify that irregular heart rhythm you just felt, you may have come across the term Normal Sinus Rhythm, or Sinus Rhythm. With your trusty watch ECG now in hand, you may be wondering, "What does Sinus Rhythm look like on my watch ECG?" In this guide, we'll help you see Sinus Rhythm on your watch ECG. Let's dive in.
What's Sinus Rhythm?
Before trying to identify Sinus Rhythm on your ECG, it's helpful to remind yourself what Sinus Rhythm actually is. (If you're confident in your Sinus Rhythm knowledge, though, skip on ahead to the next section for some visual examples of a Sinus Rhythm ECG).
To start, remember how your heart beats? It produces an electrical signal, which squeezes and unsqueezes your heart, which in turn pumps your blood to your lungs for oxygen and then out to the rest of your body.
With Sinus Rhythm, that electrical signal is produced completely normally and correctly by your heart's "sinus node." You can think of your heart's sinus node as your heart's natural pacemaker.
Sinus Rhythm is the rhythm of a normal, healthy heart. It means the electrical pulse generated by your heart's sinus node moves properly through the rest of your heart, causing it to squeeze and unsqueeze smoothly and healthily.
So What Does Sinus Rhythm Look Like on My Watch ECG?
To identify Sinus Rhythm on your ECG, look for these tell-tale signs:
- A heart rate between 60 and 100 beats-per-minute (bpm).
- A regular R-R interval, or the distance between the peaks of your QRS complexes.
- A normal P wave, that comes immediately before your QRS complex.
- A normal PR interval, which is normally between 0.12 and 0.20 seconds long.
- A normal QRS complex, which is normally between 0.08 and 0.12 seconds long.

What's the Difference Between Sinus Rhythm and Heart Rate?
Your heart rate is the number of times your heart beats per minute. A resting heart rate of 60 to 100 bpm is considered normal for most people, although athletes or people who stay fit with frequent exercise can see a lower resting heart rate in the 40s and 50s.
Sinus rhythm, on the other hand, refers to your heart rhythm. Your heart rhythm is the pattern of how your heart beats, beyond simply your heart rate. Your heart rhythm includes other clues, like your PR interval, your QRS interval, your QT interval, and the presence of irregular heartbeats or ectopic beats.
Is Sinus Rhythm a Cause for Concern?
Not at all. Sinus Rhythm means your heart is functioning properly and healthily 🙂
