Ventricular fibrillation - Causes and Risk Factors

Ventricular fibrillation is characterised by very fast and very irregular heartbeats. It is a form of arrhythmia and is usually due to poor functioning of the heart’s ventricles. A patient could lose consciousness within seconds and die within minutes.

Common causes of ventricular fibrillation include:

High risks of coronary artery disease
Poor heart function and heart failure
Strong Family history of SCD (including genetic disorder of the heart muscles (e.g. Hypertrophic cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy)
Electrical disorders of the heart (e.g. Wolff-Parkinson-White syndrome) or inherent abnormality of membrane of the heart muscle cells specialised in conduction (e.g. Brugada Syndrome and congenital long QT syndrome)
Severe metabolic derangement (e.g. Severe hyperkalemia)
