Heart Action Potential: Ventricular Muscle vs. SA Node | Cardiac Electrophysiology

Understanding the action potential of the ventricular muscle and SA node is crucial for grasping cardiac physiology. In this lecture, I explain: ✅ The phases of ventricular and SA nodal action potential and their ionic basis ✅ The role of SA node action potential in heart rhythm ✅ The differences between ventricular and SA nodal action potential ✅ The importance of ion channels (Na+, K+, Ca2+) in cardiac electrophysiology This video is designed for medical, dental, nursing, and health science students preparing for exams and clinical practice. Whether you're studying for the USMLE, PLAB, MBBS, BMLS, nursing or other exams, this comprehensive lecture will help you understand cardiac action potentials.
