Quizplus · Accepted Answer

Second-degree AV block, Mobitz type II is the type of heart block that tends to progress quickly to third-degree AV block or complete heart block. This is because there is a more advanced block in the conduction system, which can completely block the signal from the atria to the ventricles. As a result, third-degree AV block may occur, which is a complete disassociation between the atria and the ventricles.
