Is supraventricular tachycardia svt completely treatable?

In most cases: Either conservatively with medications or with radiofrequency ablation which has a very high cure rate.

Often: Electrophysiologists like myself specialize in the definitive treatment of these arrhythmias. If it is one of the 3 common types, success rates of an invasive procedure can be 85-98% with a relatively low risk of recurrence. As always, an excellent electrophysiologist is recommended to maximize your chances of success and minimize the risks.
