How can supraventricular tachycardia be treaated with medication?

Various med: Meds for svt fall into 2 major categories: those that slow conduction through the av node (beta blockers and calcium channel blockers) and anti-arrhythmics that alter ion currents such as flecainide, Propafenone and others. The first group is cheap and has no dangerous side-effects. The second group is expensive and has the potential for serious side-effects in some people.

Electrical behavior: Depending on what type of supraventricular tachycardia (svt) you have and whether treatment is chronic (every day prevention) or on an emergency basis, medication is available that either works by slowing down you heart rate overall or interferes with the transmission of electricity between your heart's upper and lower chambers thereby braking the cycle that allows svt.
