Let's dive into the cardiac action potential and how it results in the contraction of the heart. We'll talk about the signal that starts at the SA node and spreads throughout the heart. We'll also get into the phases of depolarization, the plateau, and repolarization and how calcium release results in muscle contraction.

Anemia is a condition where the body doesn’t have enough healthy red blood cells. Iron-deficiency anemia is a type of anemia that develops if you don't have enough iron in your body. In this video, I explain the pathophysiology, what causes it, and how it's treated.
