That's correct. 2nd Degree Heart block Type 1 (Wenkebach) has a gradually increasing PRI until finally a QRS is dropped. However, 2nd Degree Heart block type 2 (Mobitz II) has a constant PRI with dropped QRS complexes.
Okay...tell me if i have it...the main feature in 2nd degree type I is that the PRI keeps getting longer, whereas in type II PRI is consistent? am I way off or on the right track?
This is mostly likely called 'Mobitz type II' phenomenon, if i'm not mistaken, where occasionally there is an atrial contraction without a subsequent ventricular contraction. Meaning that, the upper 2 chambers of the heart contract but not followed by a contraction of the lower 2 chambers, as should normally occur, and so there is a missing peep noticed at the third beat, the missing contraction. (missing QRS complex after the 3rd P wave).
