In some SVTs the atria may spontaneously generate multiple rapid impulses. Many of these impulses can travel through the AV node to the ventricles in an erratic manner. As a result, the heart rhythm can become irregular and rapid. If this happens, the heart will not pump blood efficiently. Treating SVT There are several ways to treat SVT, including medications, surgery, and ablation.
Antiarrhythmic medications change how the heart's electrical system works.
They can help prevent abnormal heartbeats from starting or being sustained. During such an operation, surgeons either cut or remove the extra electrical pathways causing the arrhythmia. Catheter ablation is another procedure in which these extra electrical pathways are destroyed. It is performed without surgery. Your physician will discuss the benefits and risks of the different procedures and help you to decide which treatment to pursue.
