The Cardiac Conduction System — ECG Academy Lesson

The most important lesson in Module 2. Trace the electrical pathway from SA node to Purkinje fibers and map each structure to what you see on the monitor.

Learning Objectives

• Trace the cardiac conduction pathway from SA node to Purkinje fibers
• Define automaticity and explain the pacemaker hierarchy
• State the inherent firing rates of the SA node, AV junction, and ventricles
• Map each conduction structure to its corresponding EKG waveform component
