Ventricular flutter

Introduction

  • Ventricular flutter is an extreme form of ventricular tachycardia (VT), with a loss of organised electrical activity
  • It is usually associated with hemodynamic collapse

  • It usually quickly degenerates to ventricular fibrillation

  • It is generally caused by a reentry mechanism

ECG characteristics

  • It is usually not possible to distinguish the P wave, QRS complex, ST segment and T wave.
  • It has a rapid frequency at approximately 200-300/min
  • It usually has a sinusoidal pattern

Management

  • approach is equivalent to a patient with Ventricular fibrillation = DC version
