This module prepares students to identify and understand clinically significant cardiac dysrhythmias and their appropriate management. Students will explore atrial dysrhythmias including atrial fibrillation, premature atrial contractions (PAC), and atrial flutter, learning to distinguish their characteristic ECG patterns and treatment approaches. The module covers paroxysmal supraventricular tachycardia and Wolff-Parkinson-White syndrome, along with their specific management strategies. Students will examine sinus dysrhythmias including bradycardia and tachycardia, life-threatening ventricular rhythms such as ventricular tachycardia and ventricular fibrillation, and their emergency treatments. The module also addresses atrioventricular (AV) blocks from first through third degree, as well as asystole and its management. Through this comprehensive exploration, learners will develop critical ECG interpretation skills necessary to recognize dangerous cardiac rhythms, understand their clinical implications, and respond appropriately in acute care situations.
