What does SVT stand for?

• A. Supraventricular Tachycardia
• B. Supraventricular Transient Tachycardia
• C. Sinus Tachycardia
• D. Slow Ventricular Tachycardia

Answer: (A)

SVT stands for supraventricular tachycardia, a rapid heart rate that originates above the ventricles—in the atria or the AV node. This is the standard term used to describe fast rhythms due to reentrant circuits or focal atrial activity, such as AV nodal reentrant tachycardia, AV reciprocating tachycardia, or focal atrial tachycardia. The other ideas don’t fit because “transient” isn’t part of the official expansion of the acronym, and sinus tachycardia is a specific mechanism from the SA node rather than a broad supraventricular category. Slow ventricular tachycardia is incorrect because VT originates in the ventricles and is typically fast, not slow, and is categorized differently.
