EMS 164 - ECG Rhythm Analysis & Interpretation for EMS Professionals

Description: Overview of the anatomy and physiology of the cardiovascular system and electrophysiology of the cardiac conduction system for Emergency Medical Service professionals. Basic electrocardiograph (ECG) multi-lead acquisition, analysis, and interpretation of various dysrhythmias and cardiovascular conditions. 

Corequisite: BIO 160  or AHS 160 , EMS 162 , EMS 201 , EMS 239 , EMS 271 , and EMS 271L  

Credits: 3
Lecture: 3
Lab: 0

Course Content:
  1. Anatomy and physiology of the cardiovascular system: pulmonary circulation, systemic circulation, effects of the autonomic nervous system and cardiovascular physiology (sequence of blood flow through the heart, cardiac cycle, stroke volume, cardiac output, preload and afterload, Frank-Starling Law, and receptor sites)
  2. Basic electrophysiology: basic myocardial cell groups, primary properties of cardiac cells (automaticity, excitability, conductivity, contractility), major ions that affect cardiac function, movement of ions, cardiac depolarization, cardiac repolarization, and refractory periods
  3. Electrical conduction system of the heart: location and function of each structure of the electrical conduction system of the heart, and normal pathway of an impulse through the electrical conduction system of the heart
  4. The electrocardiogram (ECG): the basics of ECG monitoring, types of ECG leads, grids and markings on ECG graph paper, ECG waveforms, correlating ECG wave forms to cardiac events, steps to analyze the ECG tracing, calculate heart rate and heart rhythm, and causes of artifact
  5. Analysis and interpretation of ECG rhythms and cardiovascular conditions
  6. ECG rhythm interpretation and differential diagnosis for the acute coronary syndromes

Learning Outcomes:
