Your child will have his or her heart rhythm checked over 24 to 48 hours. This test is done to check the heart during exercise. He or she will walk on a treadmill or pedal a stationary bike while the ECG is recorded. Your child is attached to the ECG machine as described above. The ECG records the heart's electrical activity for a minute or so. Your child will lie down while electrodes are connected to the ECG machine by wires. This simple test measures the electrical activity of the heart. An ECG may show an arrhythmia. Your child may need tests, including:Įlectrocardiogram (ECG). This is a doctor with special training to treat children with heart problems. Your child may need to see a pediatric cardiologist. The provider will give your child an exam focusing on the heart. He or she look for signs and symptoms of an arrhythmia. Your child's healthcare provider will ask about your child's health history and family history. How is an arrhythmia diagnosed in a child? Make sure your child sees his or her healthcare provider for a diagnosis.
The symptoms of an arrhythmia may look like other health conditions or heart problems. For those who do, these are the most common symptoms:įeeling like the heart is fluttering (heart palpitations) What are the symptoms of an arrhythmia in a child?Ī child with an arrhythmia may not have any symptoms. Normal reaction to exercise, fever, or emotions Heart problem that is present at birth (congenital)Ībnormal levels of certain chemicals in the blood The cause of an arrhythmia may be unknown. This problem may happen after heart surgery or be caused by heart disease. The heart usually beats considerably more slowly. The electrical signal from the upper to lower chambers is blocked. A child with symptoms may be tired or dizzy, or may faint.Ĭomplete heart block. It may occur in children who have had open heart surgery. The heart's natural pacemaker (sinus node) doesn't work as it should. He or she may also feel his or her heart beat (palpitations). A child may feel weak, tired, dizzy, or may faint (syncope). It is caused by a very fast electrical signal from the ventricles. This is a potentially life-threatening arrhythmia. This is an abnormal electrical signal that gets to the ventricle over an extra electrical pathway. Treatment may be needed if it happens often or lasts long. An abnormal electric circuit or focal site in the atria can cause rapid heart rates. This is the most common tachycardia in children. Supraventricular tachycardia (SVT), paroxysmal atrial tachycardia (PAT), or paroxysmal supraventricular tachycardia (PSVT). Sinus tachycardia. A fast heart rate that occurs with fever, excitement, and exercise. Often, they are considered completely normal and harmless. PACs or PVCs are abnormal beats that start in the upper chambers of the heart (atria) or the lower chambers of the heart (ventricles). Premature atrial contraction (PAC) and premature ventricular contraction (PVC). Many children have no symptoms, but fainting is common in those who do. It usually affects children and young adults. This is a condition passed from parents to children (inherited). And the organs can't work as well and may become damaged.
That means the brain, lungs, and other organs may not get enough blood. When the heart doesn't beat normally, it isn't able to pump blood to the body as well. In an arrhythmia, abnormal electrical signals through the heart muscle may cause the heart to beat too fast (tachycardia), too slow (bradycardia), or irregularly. Arrhythmias in Children What are arrhythmias in children?Īn arrhythmia is an abnormal rhythm of the heart.
