Introduction
The world of wearable technology is in a constant state of evolution, offering us invaluable health data right on our wrists. Your watch ECG can reveal fascinating details about your heart's rhythm, such as Wenckebach and a sinus pause of more than three seconds. These two conditions, often discussed in terms of "Wenckebach vs Sinus Pause," look different on an ECG and can have different implications for heart health. Let’s dive in.
What’s Wenckebach?
Wenckebach, or Mobitz Type I, is a type of Second-Degree Heart Block. It's characterized by progressive prolongation of the PR interval until a beat is dropped (a P wave is not followed by a QRS complex). On an ECG, you will observe a repetitive pattern: each PR interval is longer than the one before until a QRS complex is missed, at which point the cycle starts anew. Here’s more on what Wenckebach looks like on your watch ECG.
What’s Sinus Pause >3 Seconds?
In contrast, a sinus pause greater than three seconds represents a break in sinus node activity, which leads to a pause in the heart's electrical activity. On an ECG, this appears as an absence of P waves and QRS complexes for a duration exceeding three seconds. Here’s more on what sinus pause >3 seconds looks like on your watch ECG.
