3rd degree heart block has consistent intervals between p waves and between QRS complexes that are independent from each other, hence the recommendation to get out the calipers. When taking exams on which I had to analyze rhythms I would take a piece of paper and place a mark above 2 consecutive p waves and move from p-wave pair to p-wave pair to see if they were consistent, and would do the same for the QRS complexes.
I would've preferred to see a longer rhythm strip in conjunction with the 12-lead to firm up this diagnosis - sometimes the switch from lead to lead on the printout can make identifying 3rd degree block more difficult than it should be.
