Question 1

What is the normal resting heart rate range for a 2-year-old child?

Accepted Answer

80-130 bpm

Answer

The normal resting heart rate for a toddler aged 1-3 years is approximately 80-130 bpm, which is higher than adult norms.

Question 2

Which ECG characteristic is most typical of supraventricular tachycardia (SVT) in children?

Accepted Answer

Narrow QRS complex at 220-300 bpm with absent or abnormal P waves

Answer

SVT in children typically presents with a narrow QRS complex, a very rapid rate (often 220-300 bpm), and P waves that are absent or hidden in the T wave.

Question 3

A 6-year-old presents with sudden palpitations and a heart rate of 230 bpm; ECG shows narrow QRS complexes with no identifiable P waves. What is the most likely rhythm?

Accepted Answer

Supraventricular tachycardia

Answer

SVT characteristically presents as a very rapid narrow-complex tachycardia with absent or retrograde P waves and an abrupt onset in children.

Question 4

What is the preferred vagal maneuver for SVT in an infant?

Accepted Answer

Ice water facial immersion

Answer

Ice water facial immersion (diving reflex) is the safest and most effective vagal maneuver for infants because it does not require patient cooperation.

Question 5

What is ventricular tachycardia (VT) characterized by on ECG?

Accepted Answer

Wide QRS complex (≥0.09 sec in children) at a rate greater than 120 bpm

Answer

Ventricular tachycardia is defined by a wide QRS complex (≥0.09 sec in children) at a rate greater than 120 bpm, originating from the ventricles.
