This can trigger palpitations, which are fluttering heartbeats &mdash; the feeling that the heart has skipped a beat or is beating irregularly. In most cases, these types of palpitations are harmless.</p> <p>Sometimes, palpitations are due to&nbsp;an abnormal heart rhythm (<a href="https://kidshealth.org/ws/RadyChildrens/en/parents/arrhythmias.html/">arrhythmia</a>) and may be a sign of a serious medical condition. Arrhythmias can be caused by heart disease, genetic factors, chemical imbalances in the blood, infections, medications, and injuries to the heart.</p> <p>Frequent palpitations or palpitations along with fainting, chest pain, sweating, or shortness of breath might indicate an arrhythmia that should be diagnosed by a doctor.</p> <h3>Keep in Mind</h3> <p>Most palpitations won't require any treatment. If an arrhythmia is causing the palpitations, treating its cause&nbsp;usually will stop the palpitations. Palpitations occurring repeatedly or with other associated symptoms should be evaluated by a doctor.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
