What is Defibrillation And Cardioversion

Purpose of Defibrillation and Cadioversion

Defibrillation is to treat lethal arrhythmia such as pulseless ventricular tachycardia and ventricular fibrillation.

Scope of Defibrillation and Cadioversion

For Ventricular Fibrillation and Pulseless Ventricular Tachycardia.

Definition – Defibrillation Cardioversion

Defibrillation- is delivering electrical current trans thoracically through paddles to terminate lethal arrhythmias.

A defibrillator is a device that gives a high energy electric shock to the heart through the chest wall to someone who is in cardiac arrest. This is called defibrillation, and it’s an essential lifesaving step in the chain of survival.

Defibrillators are very easy to use. Although they don’t all look the same, they all function in broadly the same way.  The machine gives clear spoken instructions.

Cardioversion- is a procedure that can restore a fast or irregular heartbeat to a normal rhythm. A fast or irregular heartbeat is called an arrhythmia. Arrhythmias can prevent your heart from pumping enough blood to your body. The success rate of cardioversion depends on the type of arrhythmia it’s used to treat.

Cardioversion is usually a scheduled procedure that’s performed in a hospital, and you should be able to go home the same day as your procedure. For most people, cardioversion quickly restores a normal heart rhythm.

Requirements / Equipments

  • Crash Cart.
  • ECG Machine.
  • Jelly
  • Cardiac Monitor
  • Ambu Bag with Tubing
  • Suction Equipment
  • Oxygen Source
  • Disinfectant for Hand Hygiene


  • Verify ECG reading.
  • Gather equipments needed, cable and monitor.
  • Apply jelly to the paddles. Place paddles firmly on patient’s chest and to upper right to sternum and the other below the left nipple in Anterior Axillary line.
  • Set energy level at 200J and as per requirement for initial defibrillation.
  • Instruct all care givers to clear out of bed.
  • Simultaneously depress the discharge controls to release the electric current.
  • Assess patients pulse and rhythm.
  • If defibrillation is unsuccessful charge to biphasic 200J and still if unsuccessful charge to 360J
  • If defibrillation is unsuccessful initiate CPR.
  • Record time and date of dysrhythmia, patient’s status before and after Dysrhythmia, time and amount of energy delivered.
