In this online course, you will learn about the phases of cardiac myocyte action potential, the factors that influence them, and the mechanisms that underlie re-entry circuits. This course has been developed to complement the upcoming advanced cardiology series and should be completed alongside foundational cardiology for a comprehensive overview of the anatomy and physiology of the cardiovascular system.

By the end of this course, you should be able to:

• Define the terms tachycardia, tachyarrhythmia, and re-entry.
• Identify the pathological requirements of a re-entry circuit.
• Examine key phases of the cardiac action potential.
• Examine the pathophysiology of a re-entry circuit.
