What does PSVT stand for in medical terms?

PSVT stands for Paroxysmal Supraventricular Tachycardia, which refers to a specific type of fast heart rate that originates above the ventricles, specifically in the atria or the atrioventricular (AV) node. The term "paroxysmal" indicates that the episodes of rapid heart rate occur suddenly and can be recurrent, making it distinct from other types of tachycardia that may be more sustained or chronic in nature. Understanding this terminology is essential for medical professionals, especially in the context of cardiology, since it helps in diagnosing and managing patients presenting with episodes of rapid heartbeats. This condition can have various underlying causes and may require specific interventions, such as vagal maneuvers or medications to control the heart rate, making accurate identification and terminology critical in clinical practice.
