PACs (Premature Atrial Contractions) and PVCs (Premature Ventricular Contractions) are types of irregular heartbeats or arrhythmias. PACs occur in the atria, the upper chambers of the heart, when an electrical impulse starts outside the normal conducting pathways of the heart, causing the atria to contract prematurely. This results in an early but typically harmless heartbeat. On the other hand, PVCs originate in the ventricles, the heart’s lower chambers. They also result from an electrical impulse occurring prematurely but in the ventricles, leading to an early contraction. Both conditions are common and can be felt as a skipped heartbeat or fluttering. While they are usually benign, frequent PACs or PVCs can sometimes indicate underlying heart conditions or increase the risk for more serious arrhythmias. Lifestyle changes, medication, or, in rare cases, medical procedures can help manage them if they become bothersome or dangerous.
