Supraventricular tachycardia is by far the most common heart arrhythmia seen in infants and children. There are many types of SVT, but the most common form in children occurs when there is an extra electrical connection between the top and bottom chambers of the heart, called an accessory electrical pathway.

Is SVT a birth defect?
SVT can be congenital, which means a child is born with it. Or SVT can develop later in life. Sometimes SVT happens because of other heart conditions.
Does SVT ever go away?
SVT can go away on its own, with medication, or with certain actions used to slow heart rate: holding your breath, coughing, or immersing your face in cold water.
Why does SVT develop?
SVT occurs when faulty electrical connections in the heart set off a series of early beats in the upper chambers of the heart (atria). When this happens, the heart rate speeds up very quickly. The heart doesn't have enough time to fill with blood before the chambers contract.

What causes SVT to develop?
SVT occurs when faulty electrical connections in the heart set off a series of early beats in the upper chambers of the heart (atria). When this happens, the heart rate speeds up very quickly. The heart doesn't have enough time to fill with blood before the chambers contract.
How common is SVT in newborns?
Supraventricular tachycardia (SVT) is the most common arrhythmia (abnormal heart rhythm) diagnosed in children. It is said to occur in up to 1 in 2500 children. While the problem is often congenital, meaning it is present at birth, the onset and severity of symptoms varies.
What is the most common cause of SVT?
The most common cause of SVT is an orthodromic reentry phenomenon, which occurs when the tachycardia is secondary to normal anterograde electrical conduction from the atria to the AV nodeAV nodeThe atrioventricular (AV) node is a small structure in the heart, located in the Koch triangle,[1] near the coronary sinus on the interatrial septum. In a right-dominant heart, the atrioventricular node is supplied by the right coronary artery.https://www.ncbi.nlm.nih.gov › books › NBK557664Atrioventricular Node - StatPearls - NCBI Bookshelf to the ventricles, with retrograde conduction via an accessory pathway from the ventricles back to the atrial.

How serious is SVT in newborns?
Babies with neonatal SVT may not have any symptoms and they may 'grow out' of the condition. Rarely if prolonged episodes occur, babies may go on to develop severe heart failure. The risk of lifethreatening events are even more rare. The heart has an electrical system that makes it pump.
Can SVT come out of nowhere?
The fast heartbeat may come and go suddenly, with stretches of typical heart rates in between. Some people with SVT have no signs or symptoms. Signs and symptoms of supraventricular tachycardia may include: Very fast (rapid) heartbeat.
Elliot’S Story: Supraventricular Tachycardia (Svt)
Is supraventricular tachycardia a birth defect?
SVT can be congenital, which means a child is born with it. Or SVT can develop later in life. Sometimes SVT happens because of other heart conditions.
Can supraventricular tachycardia be reversed?
Supraventricular tachycardia, or SVT, is a type of rapid heartbeat that begins in the upper chambers of the heart. Most cases don't need to be treated. They go away on their own.
