Supraventricular tachycardia SVT is an extrassistole fast heart rhythm arising from improper electrical activity in the upper part of the heart.

The main pumping chamber, the ventricleis protected to a certain extent against excessively high rates arising from the supraventricular areas by a “gating mechanism” at the atrioventricular nodewhich allows only a proportion of the fast impulses to pass through to the ventricles.

This therapy has further improved the treatment options for people with AVNRT and other SVTs with pathways close to the AV nodewidening the application of curative ablation to young patients with relatively mild but still troublesome symptoms who would not have accepted the risk of requiring a ectrasistole.

A variety of drugs including simple AV nodal blocking agents such as beta-blockers and verapamil eextrasistole, as well as anti-arrhythmics may be used, usually with good effect, although the risks of these therapies need to be weighed against potential benefits.
