Key Takeaways

  • The tell-tale sign of Ventricular Trigeminy is a Premature Ventricular Contraction (PVC) on every third beat of your heart rhythm.
  • The occasional Ventricular Trigeminy usually isn't a cause for concern, but it can lead to more serious heart conditions.
  • If you show signs of Ventricular Trigeminy, contact your healthcare provider immediately to rule out the presence of harmful underlying conditions.

Introduction

Hello, heart hero. In your quest to identify that irregular heart rhythm you just felt, you may have come across the terms Atrial Trigeminy or Ventricular Trigeminy. With your trusty watch ECG now in hand, you may be wondering, "What does Ventricular Trigeminy look like on my watch ECG?" In this guide, we'll help you see Ventricular Trigeminy on your watch ECG. Let's dive in.

What's Ventricular Trigeminy?

Before trying to identify Ventricular Trigeminy - sometimes seen as "Vent Trigeminy" - on your ECG, it's helpful to remind yourself what Ventricular Trigeminy actually is. (If you're confident in your Ventricular Trigeminy knowledge, though, skip on ahead to the next section for some visual examples of a Ventricular Trigeminy 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.

Normally, your heart produces that electrical signal from your "sinus node" to generate a normal heartbeat. Sometimes, however, that electrical signal starts from somewhere else in your heart, where it isn't supposed to. This abnormal heartbeat is called an "ectopic" heartbeat. When that ectopic heartbeat starts in your heart's lower chambers, or ventricles, it's called a Premature Ventricular Contraction (PVC). "Trigeminy" is a type of abnormal heart rhythm where an ectopic heartbeat happens every third heartbeat in the rhythm. Ventricular Trigeminy, then, is when every third beat of your heart rhythm is a PVC.

So What Does Ventricular Trigeminy Look Like on My Watch ECG?

To identify Ventricular Trigeminy on your ECG, look for these tell-tale signs:

  • Two normal heartbeats followed by a PVC, for three or more consecutive cycles. The beat pattern is: normal-normal-PVC, normal-normal-PVC, and so on.
  • A premature P wave, which can vary in size and shape.
  • A wide QRS interval.

For visual examples, take a look at Ventricular Trigeminy seen on Qaly members' watch ECGs.

Here's another Ventricular Trigeminy caught on a Qaly member's Apple Watch ECG, followed by a single PVC. The Apple Watch ECG app couldn't analyze this ECG because of a heart rate under 50.

Is Ventricular Trigeminy a Cause for Concern?

Ventricular Trigeminy typically isn't a cause for concern, often resolving on its own. However, if you experience a high burden of Ventricular Trigeminy or worsening symptoms, it may be a sign of a more serious heart condition.

As always, if you show signs of Ventricular Trigeminy, contact your healthcare provider immediately to rule out the presence of harmful underlying conditions.
