The treatment of paroxysmal supraventricular tachycardia depends in part on the underlying cause for the arrhythmia. Vagal maneuvers such as breath-holding and the Valsalva maneuver may stop paroxysmal supraventricular tachycardia. However, these maneuvers are only used in patients who have no symptoms and a stable blood pressure.
In cases that fail to respond to vagal maneuvers, the initial treatment for paroxysmal supraventricular tachycardia includes medications. A smaller number may benefit from cardioversion.
Medications for paroxysmal supraventricular tachycardia:
- Adenosine (Adenocard)
- Calcium channel blockers
- Flecainide (Tambocor)
- Propafenone (Rythmol)
- Beta-blocker medications:
- Digoxin (Lanoxin)
Additional treatment may also include:
