Heart Medications: Antiarrhythmic Agents, Part 1
Series Overview: The series focuses on the medications used to treat conditions of the cardiovascular system. It begins with an overview of the anatomy and physiology of the heart, followed by an explanation of the affects of chronotropic and inotropic agents. Drug classes used for the treatment of cardiac disorders are discussed as they relate to specific conditions and uses, including angina, hypertension, anticoagulation, heart failure, hyperlipidemia and arrhythmias. Indications, contraindications and possible adverse reactions are included. The segment on antiarrhythmics begins with an overview of the electrophysiologic properties of the heart. Patient teaching regarding the medications as well as signs and symptoms of cardiac disease and adverse drug reactions are covered. Content throughout is enhanced with animated graphics and realistic patient care scenarios.
Video Overview: This program provides an overview and discussion of the electrical properties of the heart as they relate to arrhythmias, which are abnormalities of heart rate or rhythm.
Objectives: After completing this course, the learner should be able to:
- Define arrhythmias and their related conditions.
- Understand and differentiate the various electrical properties of the heart.
- Discuss the five phases of depolarization and repolarization.
- Describe the heart's conduction system, including how and why "reentry" may occur.
