If damage to the AV node slowed down conduction through this tissue, what would be observed on an ECG?
A) a longer P wave
B) a larger P wave
C) an inverted T wave
D) a wider QRS complex
E) a longer PR interval

Question

Quizplus · Accepted Answer

The AV node is responsible for the delay between atrial and ventricular activation, which is represented on an ECG by the PR interval. If damage to the AV node slowed down conduction, it would result in a longer PR interval, as it would take longer for the electrical impulse to travel from the atria to the ventricles.
