What Does It Mean When Your Heart Skips a Beat?

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. Most people experience these occasionally, with studies showing up to 99% of healthy individuals have some premature beats on 24-hour heart monitoring. Common triggers include caffeine, stress, lack of sleep, dehydration, or certain medications. While usually harmless in healthy hearts, frequent skipped beats or those accompanied by chest pain, shortness of breath, or dizziness warrant medical evaluation to rule out underlying heart conditions.
