Supraventricular Tachycardia - Paroxysmal Supraventricular Tachycardia

What are the treatments for the condition?

Someone who experiences PSVT for the first time usually goes to the emergency department. Simple techniques often stop the PSVT. When these methods don't stop the PSVT, a medication called adenosine may be tried. This medication is given in the vein of the person with PSVT. Usually within a few seconds, the medication disrupts the abnormal electrical pathway, resulting in the return of a normal heart rhythm.

What are the side effects of the treatments?

If medication is needed, side effects may be experienced. Complications from radiofrequency catheter ablation are rare, but may include blood clots, new arrhythmias, or even a heart attack. Occasionally, a person may need a permanent pacemaker after this procedure.

What happens after treatment for the condition?

Once PSVT stops and the heart returns to a normal rate and rhythm, the person is the same as they were before the onset of PSVT. If a person has frequent or disabling PSVT, the healthcare provider may recommend radiofrequency catheter ablation.

How is the condition monitored?

Generally, monitoring is not done for PSVT. A person who experiences PSVT should notify the healthcare provider if the frequency or severity of the episodes changes.
