An arrhythmia—an abnormal heart rhythm, or irregular heartbeat—in a child can be treated in many cases with a technique called a catheter ablation. During a catheter ablation, a high-frequency electrical energy is delivered through a catheter (a small, thin tube) to a small area inside the heart that causes the abnormal heart rhythm.

What is cardiac arrhythmia?
What are Cardiac Arrhythmias? A cardiac arrhythmia is any abnormal heart rate or rhythm. In normal adults, the heart beats regularly at a rate of 60 to 100 times per minute. And the pulse (felt at the wrist, neck or elsewhere) matches the contractions of the heart's two powerful lower chambers, called the ventricles.
What are the symptoms of a ventricular arrhythmia?
Supraventricular tachyarrhythmias - These can cause palpitations (awareness of a rapid heartbeat), low blood pressure and fainting.
Where do cardiac arrhythmias originate?
Cardiac arrhythmias sometimes are classified according to their origin as either ventricular arrhythmias (originating in the ventricles) or supraventricular arrhythmias (originating in heart areas above the ventricles, typically the atria ).
What causes a slow heart rate?
Some common types of cardiac arrhythmias include: Sinus node dysfunction - This usually causes a slow heart rate (bradycardia), with a heart rate of 50 beats per minute or less. The most common cause is scar tissue that develops and eventually replaces the sinus node. Why this happens is not known.
What is the treatment for sinus node dysfunction?
Sinus node dysfunction - In people with frequent, severe symptoms, the usual treatment is a permanent pacemaker. Supraventricular tachyarrhythmias - The specific treatment depends on the cause of the arrhythmia. In some people, massaging the carotid sinus in the neck will stop the problem.

Why do we need cardiac ablation?
Why it's done. Cardiac ablation is a procedure that's used to correct heart rhythm problems. When your heart beats, the electrical signals that cause your heart to squeeze (contract) must follow a specific pathway through your heart. Any disruption in the signaling pathway can trigger an abnormal heartbeat (arrhythmia).
What is the procedure called when you have a scar in your heart?
Cardiac ablation. Cardiac ablation is a procedure that scars tissue in your heart to block abnormal electrical signals. It's used to restore a normal heart rhythm. Long flexible tubes (catheters) are threaded through blood vessels to your heart. Sensors on the tips of the catheters use heat or cold energy to destroy (ablate) the tissue.
