What is the typical heart rate range for supraventricular tachycardia?

• A. 60-100
• B. 100-140
• C. 140-220
• D. 220-300

Answer: (C)

Supraventricular tachycardia (SVT) is characterized by an abnormally fast heart rate originating above the ventricles, typically from the atria or the atrioventricular node. The typical heart rate range for SVT is between 140 to 220 beats per minute. This elevated heart rate occurs due to reentrant circuits or other mechanisms that promote rapid electrical conduction in the upper heart structures. Recognizing the hallmark heart rate range for SVT is crucial for diagnosis and treatment, as it helps differentiate it from other arrhythmias, such as atrial fibrillation or atrial flutter, which can present with different heart rate characteristics. Understanding these specific ranges allows healthcare providers to take appropriate interventions, such as vagal maneuvers or pharmacological options, to restore normal heart rhythm and stabilize the patient. While other heart rate ranges might appear in discussions about various cardiac conditions, they do not apply to the classification of SVT and fundamentally differ from the typical profile observed in this specific arrhythmia.
