What is an arrhythmia in children?

An arrhythmia is an abnormal rhythm of the heart. With an arrhythmia, an abnormal electrical signals throughout the heart muscle causes the heart to beat too fast (tachycardia), too slow (bradycardia), or irregularly. When the heart beats irregularly, blood flow is negatively impacted therefore the lungs, brain and other organs may not get enough blood.

Types of arrhythmias in children include:

Atrial flutter  is a very fast heartbeat caused by muscles contracting quickly.

Complete heart block where the electrical signal from the upper to lower chambers is entirely blocked causing the heart to beat more slowly.

Long QT Syndrome which occur when the ventricles take too long to contract and release resulting in erratic, fast heartbeats.

Premature atrial contraction (PAC) and premature ventricular contraction (PVC) caused when a premature or extra heartbeat occurs in, either, the atria or the ventricles. 

Sinus tachycardia (SVT) which is a normal increase in the heart rate often associated with exercise, fever, or excitement and typically does not require treatment.
