CVT 103 – Electrophysiology and Cardiac Anatomy

Course Description

Introduces the concepts essential in the performance and interpretation of 12 lead EKG and heart sounds. As a study of the anatomy, physiology, structural relationships, and the pathophysiology of the human heart and vascular system, the course concentrates on specialized terminology, cardiac and vascular anatomy, and electrophysiology. Topics include: heart anatomy, circulatory system, heart electrical system, heart layers, physical heart defects, electrocardiograph, preparation for various electrocardiographic and sonographic examinations, and physical principles and pathophysiology of heart sounds. Laboratory experiences will be provided.
