With atrial flutter, however, the electrical impulse begins in a circuit that moves throughout the right atrium and causes the heart to beat rapidly and abnormally.</p> <p>A rapid heartbeat can stress the heart and cause chest pain, palpitations, shortness of breath, fatigue, and low blood pressure.</p> <p>Atrial flutter is often caused by damage to the heart or by congenital (present at birth)&nbsp;heart <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/birth-defects.html/">defects</a>. Other causes include certain medications, viral infections, and metabolic disorders. In some cases, it happens for no apparent reason. It can also come and go.</p> <p>A rapid heartbeat can increase the risk of stroke or heart disease, so should be treated. Treating the cause of atrial flutter can usually restore a normal heart rate. Medications can also help slow the heart or thin the blood to reduce the risk of stroke.</p> <h3>Keep in Mind</h3> <p>Though it can be serious, if atrial flutter is treated properly, most people can live perfectly normal lives, although some may have a relapse of the condition from time to time.</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
ArrhythmiasArrhythmias are abnormal heartbeats usually caused by an electrical "short circuit" in the heart. Many are minor and not a significant health threat, but others can indicate a more serious problem.https://kidshealth.org/ws/RadyChildrens/en/teens/arrhythmias.html/79184e00-417e-4ce4-a49b-2e89de1b1bd4
Atrial Septal DefectAtrial septal defect, or ASD, is a heart defect that some people are born with. Most ASDs are diagnosed and treated successfully with few or no complications.https://kidshealth.org/ws/RadyChildrens/en/teens/asd.html/109626e5-a3cb-4cba-a44d-947c86de3a81
Atrial Septal Defect (ASD)Atrial septal defect (ASD) — also known as a "hole in the heart" — is a type of congenital heart defect. Most ASDs are diagnosed and treated successfully.https://kidshealth.org/ws/RadyChildrens/en/parents/asd.html/2853e7be-1368-420f-bc8d-134350949604
Congenital Heart DefectsHeart defects happen when there's a problem with a baby's heart development during pregnancy. Most heart defects can be treated during infancy.https://kidshealth.org/ws/RadyChildrens/en/parents/if-heart-defect.html/3dd23fa7-906f-4df9-8638-7400b77bed42

StrokesThis "brain attack" happens when blood flow to the brain stops, even for a second. Often, kids who have a stroke can learn to use their arms and legs and speak again through brain retraining.https://kidshealth.org/ws/RadyChildrens/en/parents/strokes.html/5539d27a-a31c-459d-9bfc-94b934761cda
