The Daily PANCE PANRE Question 29

Upon review of an EKG, you notice periodic, repetitively absent QRS complexes and "grouped beating." Which of the following is the explanation? Third-degree heart block Mobitz Type II heart block Mobitz Type I heart block First-degree heart block Sinus tachycardia Answer: C Mobitz Type I heart block I don't like the wording of this question, but typically "group beating" suggests Wenckebach. The fact that there are absent QRS complexes means there is a second or third degree AVB. In Mobitz II, the PR intervals are the same - so no "grouped" beating, in Third degree, there is no rhyme or reason to the rhythm. In Wenckebach, the rhythm "repeats", causing a "regularly irregular" rhythm.
