• A to Z: Wolff-Parkinson-White (WPW) Syndrome

  Learn about Wolff-Parkinson-White Syndrome, a congenital heart condition that can cause an abnormally fast heart rhythm known as supraventricular tachycardia.

• A to Z: Ventricular Tachycardia

  Learn about ventricular tachycardia, a potentially life-threatening arrhythmia in which the heart beats too rapidly.

• A to Z: Ventricular Septal Defect (VSD)

  Learn about congenital heart defects and conditions that affect the heart and circulatory system.

• A to Z: Truncus Arteriosus

  In the womb, a child's heart may develop a single large artery rather than separate aortic and pulmonary arteries. Learn about the condition here.

• A to Z: Tetralogy of Fallot

  Learn about tetralogy of Fallot, a rare congenital heart disorder.

• A to Z: Tachycardia

  Learn more about types of arrhythmias and problems of the heart.

• A to Z: Pulmonic Valvular Stenosis

  Learn about this congenital heart defect that alters blood flow through the heart and lungs and can affect a child's growth and circulation.

• A to Z: Pericarditis

  Learn about complications of infections and conditions that affect the heart.

• A to Z: Paroxysmal Supraventricular Tachycardia (PSVT)

  Paroxysmal supraventricular tachycardia (PSVT) is a type of arrhythmia in which the heart beats very rapidly.

• A to Z: Patent Ductus Arteriosus (PDA)

  Learn about heart conditions that affect newborn and premature babies.

• A to Z: Palpitations

  Learn about arrhythmias and conditions that affect the heart and heartbeat.

• A to Z: Kawasaki Disease

  Learn about Kawasaki disease, an illness that involves the skin, mouth, and lymph nodes.

• A to Z: Interrupted Aortic Arch

  Read about this condition in which the aorta has developed in a way that divides it into two parts and interrupts the proper flow of blood.

• A to Z: Hypoplastic Left Heart Syndrome

  Learn about hypoplastic left heart syndrome, a rare and serious defect of the heart.

• A to Z: Hypertension, Pulmonary

  Learn about types of high blood pressure and conditions that can affect the lungs and heart.

• A to Z: Hypertension, Primary

  Learn about types of high blood pressure and conditions that can affect the heart and blood vessels.

• A to Z: Ebstein’s Anomaly

  Learn about Ebstein's anomaly, a rare defect in the right side of the heart that is present at birth (congenital).

• A to Z: Dysrhythmia

  Learn more about dysrhythmia: an abnormality in the heart's beat or rhythm caused by electrical impulses functioning improperly.

• A to Z: Complete Transposition of the Great Vessels

  In this condition that starts in the womb, reversed connections of the aorta and pulmonary artery prevent the blood from getting oxygen. Learn more here.

• A to Z: Coarctation of the Aorta (COA)

  Learn about coarctation of the aorta, a treatable congenital heart defect in which a person's aorta is narrowed at some point.

• A to Z: Cardiomyopathy

  Learn about cardiomyopathy, a disease in which the heart muscle becomes weak and enlarged, making it difficult to pump blood through the body.

• A to Z: Cardiomegaly

  Diseases can put added strain on the heart. As it enlarges to pump more blood to the body, the heart muscle weakens and does not work well in this condition. Read more here.

• A to Z: Cardiac Arrest

  With this medical emergency, the heart suddenly stops beating and prevents oxygen from getting to the body. Read more about it here.

• A to Z Symptom: Chest Pain

  Most causes of chest pain in kids and teens are not serious and will clear up with minimal or no treatment.

• A to Z: Aortic Stenosis

  In aortic stenosis, the aortic valve is narrower than it's supposed to be and can't open all the way.

• A to Z: Atrioventricular Septal Defect

  Learn about congenital heart defects and conditions that affect newborn babies.

• A to Z: Atrial Septal Defect (ASD)

  Learn about congenital heart defects and conditions that affect the heart and circulatory system.

• A to Z: Atrial Flutter

  Atrial flutter is an abnormal heart rhythm that causes the heart to beat too fast.

• A to Z: Atresia, Tricuspid

  Learn about congenital defects and conditions that affect vessels, valves, and passages in the heart and other organs.

• A to Z: Atresia, Pulmonary

  Learn about congenital defects and conditions that affect vessels, valves, and passages in the heart and other organs.

• A to Z: Atresia, Aortic

  Learn about congenital defects and conditions that affect vessels, valves, and passages in the heart and other organs.

• A to Z: Arrhythmia

  An arrhythmia is an abnormal heart rhythm usually caused by an electrical "short circuit" in the heart.

• A to Z: Acute Febrile Mucocutaneous Lymph Node Syndrome (MCLS)

  See: Kawasaki Disease.
