134 EKG Interpretation and Response

© 2015

This four-part series provides healthcare professionals with the knowledge and skills needed to interpret heart rate and rhythm waveforms obtained via Lead II of a 3-Lead, 5-Lead, or 12-Lead EKG. 

Program one begins with a description of the heart’s anatomy and physiology with emphasis on its electrical conduction system.  A detailed description of the various EKG systems - 3-Lead, 5-Lead, and 12-Lead - is presented along with the 7-step method for Lead II interpretation.

The other three programs focus on cardiac dysrhythmias and their associated Lead II EKG interpretations, including sinus arrhythmia, sinus bradycardia, sinus tachycardia, atrial fibrillation, atrial flutter, junctional dysrhythmias, First degree heart block, Second degree heart block Mobitz type I, Second degree heart block Mobitz type II, Third degree heart block, ventricular tachycardia, ventricular defibrillation, asystole, and pulseless electrical activity.  The pathophysiology of each dysrhythmia and its interventions are also explored.

Still art and animation are used to enhance the material and rhythm strips are utilized throughout to illustrate the variances in the waveform for each pathology as well as demonstrate the 7-Step Method of rhythm interpretation. Wide-screen.

Schools:  Advanced:  coronary care

Healthcare Facilities: 
Orientation all critical care units, step down unit, ED; monitor observer training; ACLS review
