Question: 1 / 50

What does a prolonged QRS complex indicate?

Conduction is impaired within the ventricles

A prolonged QRS complex indicates that there is impaired conduction within the ventricles. This can be caused by various electrolyte imbalances, structural heart defects, or medications. Options B and C are incorrect because they refer to heart rate, not conduction within the heart. Option D is incorrect because it refers to atrial contractions, which are not affected by a prolonged QRS complex.
