SVT stands for which arrhythmia?

• A. Supraventricular Tachycardia
• B. Sinus Tachycardia
• C. Supraventricular Trans Tachycardia
• D. Systemic Vascular Tachycardia

Answer: (A)

SVT refers to a rapid heart rhythm that originates above the ventricles, meaning from the atria or the AV node. This group is typically characterized by a fast, regular rate with narrow QRS complexes. That’s why the term SVT stands for Supraventricular Tachycardia. Sinus Tachycardia, while also fast, is a normal physiologic response driven by the sinus node and not an abnormal supraventricular tachycardia. The other options aren’t standard terms (one is a misspelling, the other isn’t a recognized arrhythmia).
