High-Risk Rhythms: EMS Recognition and Management of Tachyarrhythmias and Fibrillation

Cardiac arrhythmias remain one of the leading causes of sudden cardiac arrest and prehospital mortality. EMS professionals are frequently the first healthcare providers to identify and manage tachyarrhythmias and life-threatening fibrillation rhythms in the field. Early recognition, accurate ECG interpretation, and appropriate intervention significantly impact survival outcomes.

This 2-hour continuing education course is designed for EMTs, AEMTs, and Paramedics and provides an in-depth review of tachyarrhythmias and fibrillation rhythms encountered in the prehospital environment. Participants will review electrophysiology fundamentals, differentiate narrow and wide complex tachycardias, recognize atrial and ventricular dysrhythmias, and apply evidence-based treatment strategies consistent with current ACLS and Texas EMS protocols.

Objectives

Upon successful completion of this course, participants should be able to:

  1. Differentiate narrow-complex from wide-complex tachycardias using QRS duration criteria.
  2. Identify the primary electrophysiologic mechanisms responsible for tachyarrhythmias, including enhanced automaticity, reentry circuits, and triggered activity.
  3. Recognize ECG characteristics of atrial fibrillation, atrial flutter, multifocal atrial tachycardia, ventricular tachycardia, torsades de pointes, and ventricular fibrillation.
  4. Determine hemodynamic stability based on clinical assessment findings in patients presenting with tachyarrhythmias.
  5. Select appropriate pharmacologic interventions for stable narrow-complex and wide-complex tachycardias according to ACLS-aligned EMS protocols.
  6. Identify indications for synchronized cardioversion versus unsynchronized defibrillation in unstable tachyarrhythmias.
  7. Identify clinical risks associated with prolonged QT interval and torsades de pointes.
