SVT is described as a sign of which condition in children?

• A. Cardiogenic shock
• B. Dehydration
• C. Asthma
• D. Sepsis

Answer: (A)

SVT in a child is a signal that the heart may not be delivering enough blood to the body. When the heart races, there’s less time for the ventricles to fill between beats, so the amount of blood pumped with each beat drops. If this rapid rhythm occurs with signs of poor perfusion—cool/clammy skin, weak pulses, delayed cap refill, or altered mental status—the situation reflects cardiogenic shock, where the heart isn’t pumping effectively to meet the body's needs. Other causes of quick heart rate, like dehydration, asthma, or sepsis, can cause tachycardia, but they don’t usually present as a rhythm disturbance that directly and acutely cripples cardiac output in the same way. So, the presence of SVT with signs of compromised perfusion points to cardiogenic shock in a pediatric patient.
