Intro to EKG/ECG Mr. McKenney, BS, RRT Associate Professor of Respiratory Care V-Tach in real time Terminology Segment = Does not include the previous wave nor the following wave Interval = Includes the previous wave but not the following wave Complex = two or more waves Morphology = shape of the waveform Block = Abnormal delay or conduction Systole = Contraction phase of the heart or "depolarization" Diastole = Resting or refilling phase of the heart or "repolarization" Terminology Continued PEA = Pulseless Electrical Activity EMD = ElectroMechanical Dissociation Fibrillation = abnormal and erratic twitching of the heart muscle; quivering Anatomy and Terms Myocytes Automaticity Electrical Conduction Pathway EKG Waveforms  What the ECG will show: heart rate Feel the Rhythm: How Music Affects Movement - STAR Center rhythm signs of cardiac enlargement (heart disease) signs of heart injury (heart attack) Ischemia, Injury, Infarction The 3 I’s  Uses of an ECG to diagnose heart disease and abnormalities of the heart for monitoring and vital signs during surgery and in intensive and cardiac care units in defibrillators to detect when electrical shock should be administered  Indications for an ECG Classical Symptoms of Heart Disease: Types of CP, SOA, Palpitations, Weakness, lethargy, Syncope  Indications for an ECG to see how well the heart is pumping and contracting to check for problems with the flow of electricity through the heart to diagnose changes in the heart routinely before surgery  Indications for an ECG as part of a complete physical exam after 40 to evaluate for conditions: disturbances in heart rate and rhythm, disorders in conduction, enlargement of heart chambers, presence of myocardial infarction, and presence of electrolyte imbalance Electrolytes With segments, you talk about morphology: elevation or depression or progression of segments. An interval in an ECG is a duration of time that includes one segment and one or more waves  3. ______ 4. __________ 5. ________ 1. _____ 2. _____
