An evaluation is requested for a patient who has episodes of atrioventricular block (AVB) in the Holter-ECG study (Figure A, Figure B, and Figure C).
What disorder do you think he has?
- 1.
Mobitz II second-degree AVB
- 2.
Bradycardia-dependent AVB
- 3.
Vagally-mediated AVB
- 4.
All options correspond to the same underlying disorder, and are therefore to the same approach.
