Ventricular Tachycardia - Course # 315-9


  • The morphologic features continue with the dysrhythmia. No P wave, wide and bizarre QRS.
  • Ventricular Tachycardia occurs when the rate exceeds 100 bpm.
  • Approximately 50% of patients become unconscious at the onset of ventricular tachycardia.
  • Although patients in V Tach may be treated with a defibrillator, not all patients in Ventricular Tachycardia require this level of treatment.
  • Depending upon their level of consciousness and blood pressure. The patient may be treated with medications, synchronized cardioversion or in the worst case scenario a defibrillator and BLS/ACLS response.
  • This rhythm must always be reported whether the patient appears stable or not. (Follow your local reporting and treatment protocols)
