What is the best thing to take if i have svt do i have to take anything?

SVT: Paroxysmal svt which occurs rarely probably doesn't need drug to try and prevent. Svt that occurs more than once a month is worth treating and for some folks even if monthly or less. Treating infrequent arrhythmias takes a long time to know if the treatment is actually working, statistically if month svt can take 6 months to be sure meds working.

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.
