Defibrillation is a process that uses an electronic device to deliver an electric shock to stop an irregular, rapid heartbeat and restore a normal rhythm. It is commonly used to treat life-threatening cardiac arrhythmias like ventricular fibrillation. There are several types of defibrillators including automated external defibrillators, semi-automated AEDs, and standard defibrillators. Defibrillators can malfunction due to issues with batteries, paddles, electronic components, cables, or control buttons. DC shock has advantages over AC pulses in that it may reduce damage to the heart and skeletal muscle convulsions.

2. Definition
Defibrillation is a process in which an
electronic device sends an electric shock to
the heart to stop an extremely rapid
irregular heartbeat, and restore the normal
heart rhythm .
Defibrillation is a common treatment for life
threatening cardiac dysrhythmias,
ventricular fibrillation, and pulse less
ventricular tachycardia.

3. Types of Defibrillators
1. Automated External Defibrillators [AED]
2. Semi- Automated AEDS
3. Standard defibrillators with Monitor
4. Trans-venous or Implanted defibrillators

4. Hardware malfunctions
• Battery malfunction.
• Malfunction of the paddle.
• Electronic malfunctions.
• Malfunction of the ECG signal cable
• Amalfunction in one of the control
buttons .
• Power supply malfunction.

5. Equipment
• Defibrillators
• ECG monitor with recorder
• Oxygen saturation monitor
• Paddle or adhesive patch
• Conductive gel or paste
• Pulse recorder
• Suction device
• Blood pressure cuff (automatic or manual)

6. The Advantages Of DC Shock
• Can reduce the effect of damage to the heart because it does
not cause ventricular fibrillation as in AC pulses .
• Can reduce the convulsive effect on skeletal (Skeletal Muscle(
• Can be used in the treatment of supraventricular (atrial)
arrhythmias properly.
