Smartwatches aren’t just timepieces or fitness trackers anymore; they’re mini electrocardiograms on the go. By monitoring irregularities such as premature atrial and ventricular contractions, you can gain valuable insight into your heart’s rhythms. To maintain your heart health, it is crucial to distinguish between PAC and PVC heartbeats. Let’s get started.
What’s Premature Ventricular Contraction (PVC)?
When the heart experiences premature ventricular contractions, the ventricles beat prematurely. On an ECG, an early, wide, and bizarre-looking QRS complex without a P wave usually appears as an early, wide QRS complex. If you see a PVC on your watch, you’ll see this ECG.
What’s Premature Atrial Contraction (PAC)?
A premature atrial contraction is caused by early atrial contractions in the atria (upper chambers of the heart). On an ECG, P waves are typically seen just prior to QRS complexes and are accompanied by compensatory pauses. When you are wearing a PAC, your watch ECG looks like this.
What’s the Difference Between PVC and PAC?
The main difference between PVC and PAC can be seen on an ECG when looking at their points of origin. Ventricles are the source of PVCs, while atria are the source of PACs. Their ECG depictions reflect their different origins, as described previously.
A person’s overall health and the frequency and pattern of PVCs and PACs can indicate whether they are benign or a sign of a more serious underlying condition. The occurrence of PVCs or PACs on a regular basis may not signify anything serious, but frequent occurrences may indicate an underlying heart condition that should be assessed by a medical professional.
You shouldn’t confuse your watch ECG with professional medical advice, even though it can provide valuable insights. A healthcare provider should be contacted as soon as possible if you notice any persistent, abnormal rhythms on your ECG. Don’t let your heart health slip away! Stay informed, stay proactive, and take care of your heart!
