What does SVT stand for in cardiology?

SVT stands for Supraventricular Tachycardia, which refers to a group of arrhythmias that originate above the ventricles in the heart. This condition is characterized by an abnormally fast heart rate, typically greater than 100 beats per minute, that is generated by electrical impulses from the atria or the AV node rather than the ventricles.

Understanding SVT is crucial in cardiology because it can lead to symptoms such as palpitations, dizziness, or even syncope in some patients. Management of SVT often includes vagal maneuvers, medications, or procedures like catheter ablation, depending on the frequency and severity of the episodes.

The other options presented do not accurately describe the term SVT in the context of cardiology. The term "Slow Ventricular Tachycardia," for instance, conflicts with the definition of tachycardia, which implies a rapid heart rate. Sinus Ventricular Tachycardia and Systemic Ventricular Tachycardia also do not correspond to established terminology in cardiology. Thus, recognizing the correct term is essential for proper diagnosis and treatment of cardiac arrhythmias.
