Bradycardiaīradycardia is a heart rate that is too slow. It is generally not life-threatening, but severe cases may require treatment with medications or procedures. Atrial flutter is rare, but it can affect children who had previous heart surgery on the atria.Ĭhildren who have atrial flutter may have episodes of dizziness or fainting. It happens when an electrical circuit in the atria is too fast. Atrial flutterĪtrial flutter is a type of tachycardia (fast heart rate). Doctors can usually treat AFib with medications. This causes the atria (top part of the heart) to shake, and it can’t pump blood as well.ĪFib may affect children who have congenital heart defects or had previous heart surgery. With AFib, electrical impulses fire from different parts of the heart. Atrial fibrillation (AFib)Ītrial fibrillation is a quivery heartbeat. The types describe the specific rhythm abnormality or the part of the heart the arrhythmia affects. Several types of arrhythmias may affect children. In newborns and infants, signs of an arrhythmia include: Palpitations (rapid, strong or irregular heartbeat).Feeling like the heart “skipped a beat”.Children and adolescents who have symptoms may experience: If these minerals are out of balance, an arrhythmia can occur.Īrrhythmia symptoms are different for each child. Electrolyte imbalance: Electrolytes are minerals your body needs to keep a regular heart rate.Congenital heart defects: Certain congenital heart defects (present at birth) can disrupt the heart’s normal electrical pathways, leading to an arrhythmia.Children have a higher risk of an arrhythmia if the condition runs in their family. Genetics: Some arrhythmias are inherited, or passed down through families.Pediatric Arrhythmia Causes and Risk FactorsĬauses and risk factors for irregular heartbeats in children include: Arrhythmias can cause a heartbeat that is: An irregular heartbeat is known as an arrhythmia. If these electrical impulses don’t work as they should, the heartbeat may be irregular.
When the heart beats, electrical impulses travel through it.
