Complete Heart Block?

 This case is from the great ECG aficionado, Dave Richley. @DaveRichley

 

 

Regular QRS. Regular P waves. Are they dissociated?

In his words:

1. Atrial tachycardia (flat P waves I & V1; atrial rate 112/min). 

2. Wenckebach AV block and dual AVN pathways with conduction switching from fast to slow pathway explaining big jump in PR from beat 5 to 6 and beat 9 to 10.
