This is a condition known as supraventricular <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/az-tachycardia.html/">tachycardia</a> (soo-prah-ven-TRIK-yuh-ler tak-ih-KAR-dee-ah).</p> <p>Most of the time, the heart beats about 60-100 times per minute. During tachycardia, the heart beats about 150-250 times per minute.</p> <p>With WPW syndrome, the frequency and severity of episodes varies from person to person. Some people have very few episodes. Others have one or two each week. During an episode, a person can have an&nbsp;irregular heartbeat (also known as palpitations), chest pain, dizziness, shortness of breath, and <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/az-symptoms-fainting.html/">fainting</a>. In rare cases, a WPW episode can cause cardiac arrest, a condition where the heart stops pumping.</p> <p>WPW is diagnosed by tests that monitor the heart's electrical activity, and it's sometimes discovered during testing for another condition.</p> <p>Treatment for WPW usually involves medicine to coordinate the heart's electrical signals, or radiofrequency ablation, a procedure where a catheter is used to destroy the extra electrical pathway in the heart.</p> <h3>Keep in Mind</h3> <p>Some people with WPW never need treatment and have few or no symptoms. Many other cases can be treated with&nbsp;medicine. When radiofrequency ablation or surgery is needed, the results are usually successful, with patients no longer needing to take medicine.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>

Arrhythmia (Abnormal Heartbeat)An arrhythmia is an abnormal heartbeat usually caused by an electrical "short circuit" in the heart. Many are minor and not a health threat, but some can indicate a more serious problem.https://kidshealth.org/ws/RadyChildrens/en/parents/arrhythmias.html/19038a47-2ae4-48f8-8bd5-9e46150171b0
