Sudden Cardiac Arrest

Sudden Cardiac Arrest occurs when a problem develops with the internal electrical system which controls the rhythm of the heart. This causes the heart to stop beating properly and without medical treatment the person can die within minutes. People are more likely to recover if they have early defibrillation using an Automated External Defibrillator, (AED).

About AEDs

An automated external defibrillator (AED) is a portable device used to administer an electric shock to the heart and restore the heart's normal rhythm during sudden cardiac arrest. Ventricular Fibrillation (VF), the abnormal heart rhythm that most often leads to sudden cardiac arrest, is treatable. If the heart can be shocked quickly with an AED, a normal heart rhythm may be restored.

Cardiopulmonary Resuscitation (CPR)

When the heart stops beating blood is no longer being pumped to the vital organs around the body. If Cardiopulmonary Resuscitation, (CPR) is administered in the form of chest compressions blood can be supplied artificially around the body until normal functioning is restored to the heart.
