Supraventricular Tachycardia (SVT)

An abnormal heart rhythm from the top chamber of the heart (SVT) may be caused by an extra conducting (accessory) pathway within the heart or a focus that beats out of sync (atrial tachycardia) from the rest of the heart. Antiarrhythmic medication may suppress these abnormal heart rhythms to a certain degree, however, only catheter ablation (energy delivered through a catheter to destroy the abnormal focus within the heart) offers a cure for most SVTs. All heart rhythm specialists at UI Health are highly trained experts in catheter ablation.
