Caitlyn Nichols | BSN, RN, CCRN-CMC on Instagram: "Can’t talk about how antiarrhythmics work without talking about the physiology of cardiac action potentials! 🫀🤓⚡️ Lol I feel like this is one of those topics that you learn in your A&P class & feel like it will never be useful, but it is because it will help you understand how the different antiarrhythmics (amiodarone, mexiletine, sotalol, flecanide, etc) work. Understanding > memorizing any day! A cardiac action potential is the electrical signal that triggers the heart muscle to contract; it’s generated by a sequence of ion fluxes (Na+, K+, & Ca2+) through specialized ion channels in the cell membrane of cardiac muscle cells. ⚛️ In my next note sheet, I’ll go over the different antiarrhythmic classes & which part(s) of the action poten Antiarrhythmic Classes, Cardiac Action Potential, Cardiac Muscle Cell, Action Potential, Cardiac Muscle, Medical Inspiration, Workout Beginner, Note Sheet, Heart Muscle

Action Potential: A-Level Biology Revision

There are four main stages to an action potential: depolarisation, repolarisation, hyperpolarisation, and the return to resting potential. Voltage-gated ion channels are needed for these processes.
