Atrial fibrillation
Specific treatment depends on the type of SVT and can include medications, medical procedures, or surgery. Vagal maneuvers, or a procedure known as catheter ablation, may be effective in certain types. For atrial fibrillation, calcium channel blockers or beta blockers may be used. Long term, some people benefit from blood thinners (anticoagulants) such as aspirin or warfarin. Atrial fibrillation affects about 25 per 1000 people, paroxysmal supraventricular tachycardia 2.3 per 1000, Wolff-Parkinson-White syndrome 2 per 1000, and atrial flutter 0.8 per 1000.
