What are the types of ectopic heartbeats?

There are two main types of ectopic heartbeats:

• Premature atrial contraction (PAC), which results from abnormal electrical signals in the top two chambers of your heart (the atria). Healthcare providers also call PACs atrial premature beats.
• Premature ventricular contraction (PVC), which results from abnormal signals coming from the bottom two chambers of your heart (the ventricles). Healthcare providers also call PVCs ventricular premature beats.
