What is Paroxysmal Supraventricular Tachycardia (PSVT)?
Paroxysmal Supraventricular Tachycardia (PSVT) is a type of arrhythmia characterized by a rapid heart rate that originates above the ventricles. It is termed "paroxysmal" because it starts and stops abruptly. The condition involves episodes where the heart suddenly begins to beat very fast, usually between 150 and 250 beats per minute.
