Key Takeaways

  • Sinus Pause <3 Seconds is a brief interruption in the heart's natural rhythm caused by a temporary failure of the sinus node, the heart's natural pacemaker. During this pause, the heart's electrical signal is momentarily disrupted, leading to a temporary halt in heart activity for less than 3 seconds.
  • To identify Sinus Pause <3 Seconds on your watch ECG, look for a pause in heart activity for less than 3 seconds, indicated by the absence of a P wave in the underlying rhythm. Other characteristics include a normal or prolonged PR interval, narrow QRS complexes, and a generally slow to normal heart rate.
  • Typically, brief pauses in Sinus Pause <3 Seconds do not require immediate clinical intervention. However, if you experience such pauses, it's essential to consult your healthcare provider to rule out any underlying conditions. While usually benign, addressing any potential concerns with a healthcare professional ensures your heart's health and well-being.

Introduction

Hello, heart hero. In your quest to identify that irregular heart rhythm you just felt, you may have come across the term Sinus Pause <3 Seconds. With your trusty watch ECG now in hand, you may be wondering, "What does Sinus Pause <3 Seconds look like on my watch ECG?" In this guide, we'll help you see Sinus Pause <3 Seconds on your watch ECG.

What's Sinus Pause <3 Seconds?

Before trying to identify Sinus Pause <3 Seconds on your ECG, it's helpful to remind yourself what Sinus Pause <3 Seconds actually is. (If you're confident in your Sinus Pause <3 Seconds knowledge, though, skip on ahead to the next section for some visual examples of a Sinus Pause <3 Seconds 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 Pause <3 Seconds, 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 in a Sinus Pause of less than 3 seconds, the action of your sinus node fails, causing your underlying heart rhythm to pause or stop for a short period.
