EKG Doubt in understanding EKG in heart Block

Hi Friends!

Kaplan says In the First degree Heart Block there is narrowing of the RR interval progressively upto the dropped beat. On the other hand I believe that the RR interval should increase rather than decreasing because of the progressive increase in the PR interval Secondly the next line states that RR interval after the blocked beat is always less than twice the RR interval of the Conducted beat. I find the second point also Bizarre but the same explanation is given everywhere

Please Help

First degree heart block is increased duration of PR interval (more than 200 ms). Progressive lengthening of this and eventual dropped beat is called Wenkeback's phenomenon..
