MASTER ECG/EKG INTERPRETATION: A Systematic Approach for 12 Lead ECG/EKGs

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this comprehensive cardiology lecture, Professor Zach Murphy teaches you how to master ECG/EKG interpretation using a systematic approach to reading 12-lead ECGs. This lecture is designed to build confidence in analyzing cardiac rhythms, detecting abnormalities, and identifying life-threatening patterns. We begin with a review of cardiac electrophysiology and the components of a standard ECG—P wave, PR interval, QRS complex, ST segment, and T wave. From there, we introduce a step-by-step method to interpreting any ECG, starting with rate, rhythm, and axis, followed by interval analysis, waveform morphology, and chamber enlargement. The lecture emphasizes recognition of: • Normal sinus rhythm and its variants • Bradyarrhythmias and tachyarrhythmias • Conduction blocks (AV blocks, bundle branch blocks) • ST segment and T wave abnormalities indicative of ischemia, infarction, electrolyte disturbances, or pericarditis We also cover lead groupings, how to localize infarctions (e.g., anterior, inferior, lateral), and correlate clinical scenarios with specific ECG changes.
