Class IV Anti-Arrhythmic Drugs Explained: The Calcium Channel Blockers

In this video we will discuss Class IV anti-arrhythmic drugs, the calcium channel blockers (CCB). We will start by discussing what the calcium channel blockers are and their multiple mechanisms of action, including actions on the cardiac myocytes, nodal cells, and vascular smooth muscle. We will relate these mechanisms to how they change both the nodal action potential and cardiac myocyte action potential in graphical form. Lastly, we will dive into the cardioselective/non-dihydropyridines versus the non-cardioselective/dihydropyridines. We will discuss the medications within each of these classes, their separate indication profiles, and their separate adverse effect profiles. This is the fifth video in our five video series on anti-arrhythmic drugs. Check out the video for all the details!
