Which of the following is a symptom of supraventricular tachycardia?

• A. Hypotension
• B. Bradycardia
• C. Persistent cough
• D. Deep vein thrombosis

Answer: (A)

Supraventricular tachycardia (SVT) is characterized by an episode of rapid heart rate originating above the ventricles, often leading to various symptoms due to decreased cardiac output and altered hemodynamics. Hypotension, which refers to abnormally low blood pressure, can occur during episodes of SVT as the heart may not be able to effectively fill and pump blood when beating too rapidly. This condition can lead to inadequate perfusion of vital organs, resulting in symptoms like dizziness, fainting, or even shock if the tachycardia is severe and prolonged. In contrast, bradycardia, which is defined as a slower than normal heart rate, would not be a symptom of SVT since the condition is characterized by an increased heart rate. Similarly, persistent cough and deep vein thrombosis are unrelated to the direct effects of SVT; they stem from different underlying mechanisms and conditions. Hence, hypotension stands out as a direct symptom related to the compromised cardiac function during an episode of supraventricular tachycardia.
