What do P waves look like in junctional beats?

Explanation:
When the impulse starts in the AV junction, atrial depolarization travels retrogradely, opposite to normal atrial activation. That retrograde conduction makes P waves appear inverted relative to normal, and they may be hidden within or follow the QRS so they aren’t seen. So P waves in junctional beats are either inverted or absent, which is why this option is the best fit.
