An electrocardiogram (ECG) is a test to evaluate the heart. Surface electrodes, placed on the chest and torso, collect electrical currents propagated by the heart to the surface of the body. These currents are translated into the ECG waveform by the electrocardiograph. The ECG is then interpreted by a trained diagnostician.It is essential that students of clinical exercise physiology be able to use and interpret the ECG in medical settings. In this regard, clinical exercise physiology students usually take one course in either their undergraduate or graduate education. The course is presented as a comprehensive survey to give them the basic abilities needed to pass certification exams.This text and the course it is meant to accompany addresses the needs of the exercise physiologist working in a clinical setting and highlights static interpretation of rhythm strips and 12-lead ECGs. It includes traditional basic ECG, arrhythmia, myocardial infarction and all the other basic concepts provided through an easy-to-read approach on cardiac physiology and pathophysiology, cardiovascular testing procedures, cardiac pharmacology, and structural heart disease. Case studies are liberally spread throughout the text to present real-world scenarios for application of the knowledge gained. The text also presents the following:Practice strips to evaluate the ECGsIncludes learning objectives and a glossary of key termsInstructor resources include PowerPoint presentations and a test bank
