Final answer:
A second-degree Type II (Mobitz II) block can progress to a third-degree block.
Step-by-step explanation:
A second-degree Type II (Mobitz II) block is a condition where some of the electrical impulses initiated by the SA (sinoatrial) node do not reach the AV (atrioventricular) node. In this type of block, P waves are not followed by the QRS complex.
In general, Mobitz II block carries a higher risk of progression to third-degree block compared to other types of blocks. This means that it is possible for a second-degree Type II block to progress to a third-degree block, where there is no correlation between atrial and ventricular activity.
Therefore, the statement 'Second Degree Type II (Mobitz II) usually doesn't progress to third degree block' is false.
