What is the best drug treatment for svt?

Depends: Depends on the cause and teh severity of the svt. Most require no drug therapy at all and instead attention to behavioral modification targeting stress reduction and possibly some alternative therapies that assist with relaxation and stress reduction. For more severe svt's calcium channel blockers and beta blockers might be first choice.

Depends on the SVT: Svt (supraventricular tachycardia) is a generic term for rhythm disturbances originating in the top part of the heart. Typical medicines used to treat svt include beta blockers or calcium blockers. Some svts require more potent medications or an invasive procedure called ablation. The key is to capture and define the specific rhythm problem - that will dictate the treatment. Good luck.

Svt meds: there are several meds. Most commonly used ones are beta blockers.
