Electrocardiogram (ECG)

This course provides a comprehensive introduction to electrocardiography (ECG), focusing on the principles of ECG interpretation and the recognition of cardiac rhythm abnormalities. Learners will begin by exploring the fundamentals of ECG recording, including lead placement, waveform components, and measurement techniques. Core topics cover the cardiac conduction system, normal sinus rhythm, and common dysrhythmias such as atrial fibrillation, flutter, bradycardia, tachycardia, ventricular arrhythmias, and heart blocks. Through detailed explanations, ECG strip analysis, and guided examples, learners will develop the ability to identify normal and abnormal patterns, interpret rhythm disturbances, and understand their physiological basis. The course also introduces clinical considerations for recognizing life-threatening arrhythmias and appropriate initial responses in nursing contexts. Designed for clarity and practical application, this course builds confidence in reading and interpreting ECGs across healthcare settings.
