Final answer:
Paroxysmal supraventricular tachycardia (PSVT) is a type of supraventricular tachycardia that originates above the ventricles in the atria. It is characterized by rapid regular heartbeats that start and stop suddenly. Treatment options for PSVT include vagal maneuvers, medications, and catheter ablation.
Step-by-step explanation:
Paroxysmal supraventricular tachycardia (PSVT) is a type of supraventricular tachycardia that originates above the ventricles in the atria. It is an abnormal heart rhythm characterized by rapid regular heartbeats that start and stop suddenly.
PSVT encompasses atrial fibrillation, atrial flutter, and other forms of tachycardia that are initiated in the atria. It is diagnosed through tests like an electrocardiogram (ECG) or Holter monitor.
Treatment options for PSVT include vagal maneuvers, medications, and in some cases, catheter ablation.
