Cardiac Electrical Conduction System - Biology Lectures for MCAT, DAT, NEET, NCLEX

Explore the intricacies of the cardiac electrical conduction system in this comprehensive biology lecture designed for MCAT, DAT, NEET, and NCLEX preparation. Delve into the key components of the heart's electrical system, including the Sinoatrial Node (SA Node or SAN), Atrioventricular Node (AV Node or AVN), Bundle of His, Right and Left Bundle Branches (RBB and LBB), and Purkinje fibers (His-Purkinje system). Gain a thorough understanding of cardiac conductivity (Dromotropic) and its role in maintaining proper heart function. Conclude with an introduction to ECG basics, providing a foundation for interpreting electrocardiograms and understanding the electrical activity of the heart.
