What is the most common heartbeat pattern associated with heart palpitations?

The most common heartbeat pattern associated with heart palpitations is indeed often represented by premature ventricular complexes (PVCs). PVCs are extra, abnormal heartbeats that begin in the ventricles and disrupt the regular heart rhythm, leading to sensations of palpitations. Patients frequently describe these feelings as having a "skipped beat" or a fluttering in the chest, which makes PVCs a common source of palpitations in clinical practice.

While atrial fibrillation is also associated with palpitations, it is less frequently the benign cause and is often seen with more significant clinical symptoms and complications. Similarly, ventricular tachycardia is a more serious rhythm disturbance and generally manifests in patients with underlying heart disease, making it a less common cause of palpitations in a broader population. Bradycardia refers to a slower than normal heart rate, which is less commonly associated with the sensation of palpitations, as palpitations are generally linked with irregular or rapid heart rhythms.
