Final answer:
The most common paroxysmal tachycardia in people without structural heart disease is paroxysmal supraventricular tachycardia (PSVT). It is a type of arrhythmia that originates above the ventricles, often in the atria, and typically presents with sudden, rapid heartbeats. Treatment options include vagal maneuvers, medication, or catheter ablation.
Step-by-step explanation:
The most common paroxysmal tachycardia in people without structural heart disease is paroxysmal supraventricular tachycardia (PSVT). PSVT is a type of arrhythmia that originates above the ventricles, often in the atria, and typically presents with sudden, rapid heartbeats. It can cause symptoms such as palpitations, lightheadedness, and fainting.
PSVT is usually not life-threatening but can be distressing. It can be triggered by factors like stress, anxiety, caffeine, alcohol, or certain medications. Treatment options include vagal maneuvers, medication, or catheter ablation.
