SVT (SupraVentricular Tachycardia)
Supraventricular tachycardia (SVT) is a common heart rhythm disurbance where the heart beats faster than it should. This rhythm problem is usually effectively treated with medications or through a minimally-invasive surgical procedure called "catheter ablation." It is important to realize that there several types of SVT, and that SVT is a general term used to describe more benign (generally safer) rapid heart rhythms that arise above (hence where the term "supra-") the ventricles (the lower chambers of the heart). The way your SVT develops (i.e., the mechanism), determines the treatment approach for each type of SVT. A heart electrical study called an "electrophysiology study" or "EP study" can determine the exact mechanism of the SVT, where the abnormal circuit exists that causes the SVT and guide the appropriate treatment strategy during the potentially curative "catheter ablation" procedure (where a small wire is used to cauterize the cells or short-circuit in the heart responsible for the rapid heart rhythm).
