Introduction to Electrocardiograms
Exercise Sciences College of Life Sciences
Cardiovascular physiology and conduction pathways of the heart. Resting and exercise 12-lead ECG preparation, recording and interpretation of normal ECG patterns, myocardial infarctions, and common atrial and ventricular arrhythmias. This course takes an approach to understanding ECGs applicable to students in exercise science-related fields of study and occupations, including the allied health or medical professions.
Grade Rule 8: A, B, C, D, E, I (Standard grade rule)
Nervous System and Depolarization of the Heart
Explain the neural innervation of the heart and the control of heart rate. Describe the normal depolarization of the heart including conduction pathways. Describe and draw the vectors of the normally depolarized heart.
Interpretation of ECGs
Explain the "view" of the heart from the perspective of each ECG lead. Describe the normal P wave, PR segment, QRS complex, J point and T wave in each of the 12 leads of an ECG. Describe the appearance of wave forms in contiguous and reciprocal leads. Recognize a normal rhythm and the characteristics of variations of the normal sinus rhythm, early repolarization, conduction blocks, atrial and ventricular premature or junctional beats, fibrillations, tachycardias, flutters, ventricular hypertrophy, and acute coronary syndromes.
Laboratory Skills and Practices
Prepare a subject for and record a resting 12-lead ECG. Evaluate a resting ECG using the 9 Steps to Interpret an ECG.
