This can cause the heart muscle's pumping function to work erratically, which can lead to a variety of symptoms, including fatigue, dizziness, and chest pain.</p> <p>Arrhythmias can be temporary or permanent. They can be caused by several things, but also can occur for no apparent reason. Congenital (present at birth) arrhythmias sometimes are due to a <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/birth-defects.html/">birth defect</a> of the heart, but some happen even when the heart has formed normally.</p> <h3>Keep in Mind</h3> <p>Many arrhythmias don't require treatment; however, some can pose a health problem and need to be evaluated and treated by a doctor.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
