What causes a cardiac arrest?
The most common cause of a cardiac arrest is a life threatening abnormal heart rhythm called ventricular fibrillation (VF).
Ventricular fibrillation happens when the electrical activity of your heart becomes so chaotic that the heart stops pumping and quivers or 'fibrillates' instead. There are various causes of VF. These can be problems with your heart, or other causes.

Heart-related causes of VFOther causes of VF

Heart attackElectrocution
CardiomyopathyUsing recreational drugs, such as cocaine

Heart valve disease 
Acute Myocarditis (inflammation of the heart muscle)
Heart conduction disorders that make you more likely to experience abnormal heart rhythms, such as Long QT syndrome
