3-Lead ECG Interpretation: From Basics to Clinical Application

This course is a comprehensive, physiology-driven deep dive into 3-lead ECG interpretation, designed for healthcare students and clinicians who want to move beyond memorization and truly understand what the ECG is showing. You’ll learn ECG interpretation from the ground up — starting with cardiac anatomy, electrophysiology, and conduction, then applying a clear, repeatable approach to rhythm analysis. Step by step, the course walks you through normal rhythms, common arrhythmias, and life-threatening patterns encountered in real clinical settings. Throughout the course, ECG findings are consistently linked to cardiac output, patient symptoms, and clinical decision-making, helping you translate monitor data into meaningful bedside actions. This course is ideal for: • Nursing, paramedic, and medical students • Practicing clinicians building a strong ECG foundation • Learners preparing for ACLS or advanced ECG interpretation What You’ll Learn • A systematic approach to interpreting 3-lead ECGs • The physiology behind normal ECG waveforms and intervals • Recognition of sinus, atrial, junctional, ventricular rhythms, and AV blocks • Identification of dangerous arrhythmias requiring escalation • Common artifacts, monitor limitations, and pacing rhythms By the end of this course, you’ll have the confidence and structure to interpret 3-lead ECGs accurately, recognize high-risk rhythms, and know when to escalate care appropriately.
