Supraventricular Tachycardia - Treatment Overview

Treatment for atrioventricular nodal reentrant tachycardia (AVNRT)

In the case of atrioventricular nodal reentrant tachycardia (AVNRT), medicines can be taken—either daily or only when the fast heartbeat arises—or catheter ablation may be done.

If you have infrequent episodes of AVNRT that last hours but do not cause severe symptoms, your doctor may recommend that you take medicines only when you have an episode. These medicines include antiarrhythmic medicines, calcium channel blockers, and beta-blockers.

Your doctors may recommend daily doses of calcium channel blockers, beta-blockers, and/or digoxin if you have frequent episodes of AVNRT. If these medicines are not effective in stopping supraventricular tachycardia from recurring, your doctor may recommend that you take an antiarrhythmic medicine.

If you take daily medicine for AVNRT or you have significant symptoms, you may want to consider having catheter ablation.

Treatment for atrioventricular reciprocating tachycardia (AVRT)

In the case of atrioventricular reciprocating tachycardia (AVRT), including Wolff-Parkinson-White (WPW) syndrome, you can take medicines for recurrent episodes either on an as-needed or daily basis, depending on how frequently they occur. These medicines—which include beta-blockers and calcium channel blockers—are often effective in stopping or preventing episodes of AVRT. Treatment of WPW frequently requires antiarrhythmic medicines that slow electrical conduction over the extra connection.

Catheter ablation is often recommended for people who have WPW, especially those who have severe symptoms or also have atrial fibrillation or flutter.
