Pre-assessment for principles of cardiac electrophysiology
To understand the mechanism of action of antiarrhythmic drugs, it is necessary to understand cardiac electrophysiologyĀ and theĀ pathophysiologyĀ of arrhythmogenesis. Please take the following pre-assessment to gauge your understanding of principles of cardiac electrophysiology as it relates to pharmacology. If you miss two or more questions, you are strongly encouraged to review cardiac electrophysiologyĀ and theĀ pathophysiologyĀ of arrhythmogenesis from […]
Drugs for dysrhythmias
Learning goals Describe the mechanism of action (including impact on ion channel(s), electrophysiologic action potential, and electrocardiogram) of antiarrhythmic drugs. Identify generic drug names and classify them according to their Singh VaughanāWilliams cardiac antiarrhythmic class. Describe adverse effects and contraindications of antiarrhythmic drugs. Describe drug interactions of antiarrhythmic drugs. Hello and welcome! This module is […]
