cardiac arrhythmias

Topic overview

Start with the big picture

The lesson connects arrhythmia classification with treatment priorities, then explores atrial fibrillation management through rate control, rhythm control, cardioversion, and stroke prevention. It outlines how antiarrhythmic classes work and why ECG and electrolyte monitoring matter, including the risk of QT prolongation and torsades de pointes. Drug-specific considerations include amiodarone toxicities and interactions, as well as renal considerations for sotalol and dofetilide. The wider topic also covers ventricular tachycardia and fibrillation, adenosine for paroxysmal supraventricular tachycardia, and acute bradyarrhythmia care. These themes help frame medication choice around rhythm type, clinical context, and safety monitoring.

Learning objectives

  • Explain key monitoring and safety concerns associated with antiarrhythmic drug classes.
  • Summarize anticoagulation considerations around cardioversion and stroke prevention in atrial fibrillation.
  • Identify the acute management topics covered for ventricular and supraventricular tachyarrhythmias.
