Antiarrhythmic Drug Class Mnemonic and Pharmacology [Made Easy - Medical, Nursing, and USMLE]

Antiarrhythmic drug class pharmacology made easy using a mnemonic. Simple explanation for medical, nursing, NCLEX, and USMLE.

Antiarrhythmic medications (common ones listed) such as class I sodium channel blockers (procainamide and lidocaine), class II beta blockers (metoprolol), class III potassium channel blockers (amiodarone), and class IV calcium channel blockers (diltiazem) are used to treat abnormal cardiac conduction rhythms including atrial fibrillation, atrial flutter, ventricular tachycardia, and ventricular fibrillation.

Learn the pharmacology of the different classes of antiarrhythmic drugs using the mnemonic in this animation. Understand the action potential of nodal pacemaker cells including the SA node and AV node, as well as the action potentials of heart muscle cells such as atrial and ventricular myocytes. Master how the antiarrhythmic medications act on different phases of the action potential.

Omg, thank you so much! I've watched many videos on this topic but yours is the only one that didn't give me a headache

[mikaylascillion]

These pharmacology videos are amazing. Please make more!!!!

[michellesessions]

I love your videos. They are very easy to understand! Thank you so much for spending the time to make these. I will recommend your videos to anyone I know that is struggling.

[AmericanoPlease]

Thank you for this video. This visualization cleared up all the confusion on antiarrhythmics. Super helpful!

[amamuffin]

I really can’t do memorization because I need to actually understand how these meds work. Tysm

[nisreennur]

It was really amazing explanation thank you so much

[drfwprm]

thank you perfect video can someone answer this :
slowing down the influx of sodium ions into cardiac muscle cells causing a decrease in the excitability of the cells it has a beta adrenergic blocker which can cause bradycardia and bronchospasm :
sotalol
propafenone
verapamil
mexitilene
