Accelerated Idioventricular Rhythm - Ventricular Rhyth.


  • The morphologic features continue with the dysrhythmia. No P wave, wide and bizarre QRS.
  • The heart rate is between 40 – 100 bpm.
  • Note the abnormal shape and width of the QRS complexes.
  • Patients with this dysrhythmia may actually be hemodynamically stable when the heart rate is within the “normal” range. This rhythm must always be reported whether the patient can tolerate it or not.
