Module 4: EKG Waveform Interpretation Basics — ECG Academy

Learn to systematically analyze the components of a normal EKG tracing. Master the PQRST waveform, intervals, and segments that form the foundation of rhythm interpretation.

Lessons

• Systematic Rhythm Interpretation Algorithm — Learn the order of the six-step rhythm workflow first, then preview how the later lessons turn each
• ECG Paper & Grid System — Use the ECG grid as a measurement tool: convert boxes to seconds and mV, verify calibration, and man
• The P Wave: Atrial Depolarization — Use a conduction-pathway-first approach to analyze P waves: identify normal morphology, classify abn
• The QRS Complex: Ventricular Depolarization — Use QRS width and morphology to classify ventricular activation: measure duration, recognize narrow
• The T Wave & U Wave: Repolarization — Learn to identify normal and abnormal T waves, understand what repolarization means clinically, and
• Intervals: PR, QRS, QT Measurement — Master the three critical EKG intervals — PR, QRS, and QT — their normal ranges, how to measure them
• Segments: ST and PR Analysis — Understand the difference between segments and intervals, master the PR segment as a baseline refere
• Heart Rate Calculation Methods — Turn grid math into a shift-ready rate decision: choose the right manual method for regular versus i
