AV Block Type 2 Mobitz 2

At the first time, i was thinking this is AV block type 1 because as we can see there is prolonged PR-interval and there is no QRS complex that disappear. But when i consult this one to my supervisor, he said that the wave that we cam find after t-wave is not u-wave, it is also p-wave because it has the same mophology with the previous p-wave. And because it has constant prolonged PR-interval and also disappear QRS complex, the rhythm is AV Block type 2 Mobitz 2. What do you think guys?
