Ventricular fibrillation occurs when there is rapid or chaotic heartbeat due to the ventricles (lower chambers of the heart) beating too fast and losing its pump function. It is a life-threatening and emergency condition.
The main symptom of ventricular fibrillation is losing consciousness and
sudden cardiac arrest.
Another early sign of symptom is ventricular tachycardia, a very rapid, but regular heartbeat of 100 beats or more a minute occurring in the lower chambers (ventricles) of the heart. If ventricular tachycardia is left untreated, it can lead to ventricular fibrillation. Patient with ventricular tachycardia may feel palpitations, chest discomfort/pain, shortness of breath or giddiness.;
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.
