What is the rate range for paroxysmal tachycardia?

• A. 100-150 beats per minute
• B. 150-250 beats per minute
• C. 250-300 beats per minute
• D. 300-350 beats per minute

Answer: (B)

Paroxysmal tachycardia refers to a sudden onset of an elevated heart rate that typically occurs in episodes. The defining characteristic of this condition is the heart rate, which usually falls within the range of 150 to 250 beats per minute. This rate is indicative of a rapid rhythm that can include different types of tachyarrhythmias, such as atrial tachycardia or ventricular tachycardia.

The reason this rate range is significant lies in its recognition; rates below 150 may indicate more stable rhythms like sinus tachycardia, while rates above 250 may suggest more severe arrhythmias, like ventricular flutter or fibrillation, which would require different management. Understanding the nuances of paroxysmal tachycardia helps in diagnosing and treating patients effectively, as the therapeutic approach may vary significantly based on the specific type and mechanism of the tachycardia present.

In summary, the classification of paroxysmal tachycardia within the 150 to 250 beats per minute range is crucial to aid in proper identification and management of the condition.
