Signs, symptoms, EKG waveforms and interventions for sinus, atrial, and ventricular dysrhythmias, as well as heart block, are illustrated using still art, animation, real time rhythm strips, and scenarios.

INTRODUCTION
Describes the anatomy and physiology of the heart, focusing on its electrical and conduction systems. Discusses monitor leads and explains the rationale for placing them in a specific pattern on a patient's chest. The final segment concerns recognition and understanding of the EKG wave form. 23 minutes

SINUS AND ATRIAL DYSTHRYTHMIAS
The pathophysiology and symptoms of sinus arrhythmia, sinus bradycardia, sinus tachycardia, atrial flutter, and atrial fibrillation are described. Corresponding EKG waveforms are presented and explained. 20 minutes

HEART BLOCK
Describes the four types of heart block: first degree, second degree Mobitz I, second degree Mobitz II, and third degree. Illustration, animation, and case studies are used to present and discuss these pathologies. 12 minutes

VENTRICULAR DYSRHYTHMIAS
Describes three common ventricular dysthrymias: ventricular tachycardia, torsades de pointes, and ventricular fibrillation through art animation and scenarios. 13 minutes
