Supraventricular Tachycardia is characterized by what type of heart rate?

Supraventricular Tachycardia (SVT) is characterized by a rapid heart rate that originates from an area above the ventricles, specifically from the atria or the atrioventricular (AV) node. This condition typically results in a heart rate of 100 beats per minute or higher, often reaching 150 to 250 beats per minute. The term "supraventricular" itself indicates that the source of the tachycardia is located in the upper chambers of the heart, distinguishing it from other types of tachycardia that may originate in the ventricles.

By recognizing that SVT is rapid and originates above the ventricles, it becomes clear why this option is the most accurate description of the condition. In clinical practice, understanding the origin and rate of the heart's electrical impulses is crucial for accurate diagnosis and appropriate treatment.
