Why Your Heart Sometimes Skips a Beat—and When to Worry

An irregular heartbeat, known as ectopic rhythm, happens when the heart beats too soon. This common condition can feel unsettling but is usually harmless. However, in some cases, it may signal a deeper health issue. Ectopic rhythm occurs when an early heartbeat disrupts the normal rhythm. Doctors also call this extrasystole, premature atrial contraction (PAC), or premature ventricular contraction (PVC). PACs start in the heart’s upper chambers, while PVCs come from the lower chambers.

When an early beat happens, the heart often pauses briefly before the next beat. This pause makes the following heartbeat feel stronger than usual. Many people experience this occasionally, especially after drinking alcohol, consuming caffeine, smoking, exercising, or feeling stressed.

The risk of PVCs increases with age, particularly in those with a family history of the condition. People who have had a heart attack are also more likely to develop it. If the irregular rhythm continues for a long time, it may point to an underlying problem, such as heart disease or a chemical imbalance in the body. Most cases of ectopic rhythm do not require treatment and resolve on their own. But if the irregular beats persist, medical advice is recommended. A doctor can check for any hidden conditions and suggest the right steps to manage the problem.
