Antiarrhythmic drug classes mnemonic

Greetings people! 

Antiarrhythmic drugs are super tough to memorize.
Good thing is, we can imagine weird things and manage!  :D
This post is about weird drawings and memory aids that will hopefully help you lovely medicos. Here it goes!

Class I A antiarrhythmics mnemonic:
The Queen proclaims dis (this)  pyramid.
For 1 A: Quinidine, Procainamide, Disopyramide.
Queens are royalty, first class people. This helps me remember class 1 A as well.

I also think A for active and active people have potential for more duration, associating the fact that class I A drugs prolong action potential duration.
Class I B mnemonic:
I Buy Lidy's Mexican tacos.
For 1 B: Lidocaine, Mexiletine, Tocainamide.

Again, I think of B for Bored, not active people; have less or reduced potential. Associating the fact that the class I B drugs decrease action potential duration. 

Class I C mnemonic:
Can I have More Fries Please?
For 1 C: Moricizine, Flecainide, Propafenone.

Class III mnemonic:
I but.. Am sota (sort of) bretting (betting) on dofu (tofu), K (okay)?
Class 3: Ibutilide, Amiodarone, Sotalol, Bretylium, Dofetilide.
K to remember Potassium channels.

"No bad boy keeps clean."
Is a good mnemonic for Na, Beta, K, Ca blockers.

That's all! 
I have been wanting to write this post for a long time now. Glad I finally did! 
Will update for more.
