Here is a tip and story to help you remember AV blocks (continuation).

Second Degree Type 2: The P-R interval is consistent; it's just not always followed by a QRS complex.

So, you decide to have a talk with your husband. He says he is going to try to not be late. The next few times he goes out he's back on time (PR 0.12-.20) then BAM HE DOESNT SHOW UP (missed QRS).

HE IS CONSTANT BUT THEN FOR NO REASON DOESN'T SHOW UP.
