Paroxysmal supraventricular tachycardia typically presents with heart rates in which range?

• A. 150 to 250 bpm
• B. 60 to 100 bpm
• C. 100 to 120 bpm
• D. 200 to 300 bpm

Answer: (A)

Paroxysmal supraventricular tachycardia is a rapid, regular rhythm caused by a reentrant circuit near the AV node. Because the impulse travels quickly through the conduction system but remains organized, the heart rate commonly falls in the 150 to 250 beats per minute range. This pace is faster than normal resting rhythm but not as extreme as some other tachyarrhythmias, helping distinguish PSVT on ECG and in clinical assessment. Normal sinus rhythm sits around 60–100 bpm, and milder tachycardias (about 100–120 bpm) don’t fit PSVT’s typical presentation, while much higher rates (200–300 bpm) often point toward other arrhythmias or conditions. So the characteristic rate for PSVT is roughly 150–250 bpm.
