What Does It Mean When Your Heart Skips a Beat?
Medically reviewed by Andre Stone | MD, University of Pittsburgh School of Medicine on August 25th, 2026.
A heart that "skips a beat" typically refers to a premature heartbeat or palpitation that disrupts your normal heart rhythm. These irregular heartbeats, called premature atrial contractions (PACs) or premature ventricular contractions (PVCs), occur when your heart's electrical system fires early. Premature beats are common, including in many people without known heart disease, but how often they are detected varies with age, the type of premature beat, and the length of monitoring. Common triggers include caffeine, stress, lack of sleep, dehydration, or certain medications. While occasional skipped beats are often harmless, contact a healthcare professional if they are frequent, persistent, or new. Seek urgent medical care if they occur with chest pain, severe shortness of breath, fainting, or severe dizziness.
