Key Takeaways
- Sinus Tachycardia is a heart rhythm in which the electrical signal from the heart's sinus node, its natural pacemaker, occurs more than 100 times per minute, resulting in a heart rate above 100 beats per minute (bpm). A normal heart rate typically falls within 60-100 bpm.
- To recognize Sinus Tachycardia on your watch ECG, look for normal and constant P Waves and PR Intervals, along with a heart rate above 100 bpm.
- Sinus Tachycardia is normal and expected during physical activities, fever, stress, or caffeine consumption. However, if your heart rate increases past 100 bpm without an apparent reason, it may indicate Inappropriate Sinus Tachycardia, which requires further evaluation by a healthcare provider to rule out any underlying conditions.

Introduction
Hello, heart hero. In your quest to identify that irregular heart rhythm you just felt, you may have come across the term Sinus Tachycardia. With your trusty watch ECG now in hand, you may be wondering, "What does Sinus Tachycardia look like on my watch ECG?" In this guide, we'll help you see Sinus Tachycardia on your watch ECG. Let's dive in.
What's Sinus Tachycardia?
Before trying to identify Sinus Tachycardia on your ECG, it's helpful to remind yourself what Sinus Tachycardia actually is. (If you're confident in your Sinus Tachycardia knowledge, though, skip on ahead to the next section for some visual examples of a Sinus Tachycardia 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 Tachycardia, that electrical signal is produced from your heart's "sinus node" as it should be. You can think of your heart's sinus node as your heart's natural pacemaker.
But with Sinus Tachycardia, that electrical impulse from your sinus node is happening more than 100 times per minute, or in other words, at a heart rate of more than 100 beats-per-minute (bpm).
A normal heart rate typically falls within 60-100 bpm.
So What Does Sinus Tachycardia Look Like on My Watch ECG?
To identify Sinus Tachycardia on your ECG, look for these tell-tale signs:
- Normal and constant P Waves and PR Intervals.
- A heart rate above 100 bpm.
- A regular heart rhythm.

Is Sinus Tachycardia a Cause for Concern?
You've likely noticed your smartwatch ECG showing a high heart rate reading when you run, do a HIIT workout, have a fever, experience pain or stress, or just caffeinated with a cup of coffee. In these situations, Sinus Tachycardia is normal and often expected, which is why it's also called Normal Sinus Tachycardia when you know the cause of your elevated heart rate. However, if your heart rate randomly shoots up past 100 bpm for no apparent reason, this may be a sign of Inappropriate Sinus Tachycardia. Inappropriate Sinus Tachycardia is when you aren't able to identify the cause of your increased heart rate, like when you're resting on your couch with a smile and your heart rate randomly shoots up.
As always, if you show signs of Sinus Tachycardia, contact your healthcare provider immediately to rule out the presence of harmful underlying conditions.
