PSVT stands for?

PSVT stands for?

• A. Paroxysmal supraventricular tachycardia
• B. Paroxysmal ventricular tachycardia
• C. Pulmonary valve stenosis velocity test
• D. Postural supraventricular tachycardia

Answer: (A)

PSVT is a rapid heart rhythm that begins and ends suddenly, arising from above the ventricles. It stands for Paroxysmal supraventricular tachycardia, where “paroxysmal” means episodic with abrupt onset and termination, “supraventricular” means the origin is above the ventricles (atrial or AV nodal), and “tachycardia” means a fast heart rate. This is different from ventricular tachycardia, which originates in the ventricles and often has different ECG features. The other options don’t reflect the standard term: one describes a ventricular origin, another is not a recognized term, and the last uses “postural,” which isn’t how PSVT is defined.
