In people who have frequent episodes, treatment with medicines can decrease how often these occur.

What are the 3 types of SVT?

Supraventricular tachycardia falls into three main groups:

• Atrioventricular nodal reentrant tachycardia (AVNRT).
• Atrioventricular reciprocating tachycardia (AVRT).
• Atrial tachycardia.

Is SVT life threatening?

SVT is rarely life threatening. But you may need treatment in hospital if you keep having long episodes. This may include: medicines to control the episodes of SVT – given as tablets or through a vein.

Is SVT curable?

SVT symptoms — heart palpitations, chest pain, shortness of breath, dizziness or lightheadedness — can be alarming, but the condition is usually treatable and can often be cured, says Michigan Medicine electrophysiologist Rakesh Latchamsetty, M.D.

Can SVT be caused by anxiety?

Some of the classic symptoms of a panic attack — a racing heart coupled with feeling breathless and dizzy — overlap with a condition known as supraventricular tachycardia, or SVT.

What is the most common cause of SVT?

Most episodes of SVT are caused by faulty electrical connections in the heart. SVT also can be caused by certain medicines. Examples include very high levels of the heart medicine digoxin or the lung medicine theophylline. Some types of SVT may run in families, such as Wolff-Parkinson-White syndrome.

Can SVT cause stroke?

Most types of SVT aren’t dangerous on their own. One type of SVT, atrial fibrillation, can be dangerous because it can lead to blood clots, which increase stroke risk.

Which is the best first line treatment for SVT?

Vagal maneuvers are an effective first-line treatment option for SVT in younger patients who are hemodynamically stable; they can also be diagnostic for nodal-dependent SVT. Brugada criteria are sensitive and specific in helping distinguish between SVT with aberrancy and ventricular tachycardia.
