Electrical vs. Mechanical Events — ECG Academy Lesson

The monitor shows electricity, not pumping. Understand PEA and why you should never assume a normal-looking rhythm means the patient is stable.

Learning Objectives

• Distinguish between electrical depolarization and mechanical contraction
• Explain why the EKG shows only electrical activity — not mechanical pumping
• Define Pulseless Electrical Activity (PEA) and explain its clinical significance
• Apply the principle of 'treat the patient, not the monitor' to daily monitoring practice
