Question

A 12-year-old child being evaluated in the pediatric intensive care unit displays the following ECG waveform. The team interprets this as which arrhythmia?

Select the correct answer to this question.
A. Second-degree atrioventricular (AV) block, type II
B. First-degree atrioventricular (AV) block
C. Third-degree (complete) atrioventricular (AV) block
D. Second-degree atrioventricular (AV) block, type I

Answer 1

The ECG waveform displayed is indicative of Third-degree (complete) atrioventricular (AV) block. In this type of AV block, there is no correlation between atrial activity (the P wave) and ventricular activity (the QRS complex).

Step-by-step explanation:

The ECG waveform displayed by the 12-year-old child in the pediatric intensive care unit is indicative of Third-degree (complete) atrioventricular (AV) block. In this type of AV block, there is no correlation between atrial activity (the P wave) and ventricular activity (the QRS complex). The P waves are not followed by the QRS complex.
