Do we have the same ladder diagram?

 What is your interpretation?

Figure 1 - 2 leads

 This is much better viewed using full disclosure.

Figure 2 - Full disclosure

This is sinus bradycardia (atrial rate ~45 bpm), with ventricular escape/fusion beats and premature atrial complexes (conducted and nonconduted). 

Here is the proposed ladder diagram
