<b>Ventricular fibrillation and ventricular flutter</b> are a frequent rhythmic excitation of the ventricles because of the constant steady circular motions of the impulse ([[re-entry]]) in them. Most often, ventricular flutter goes into ventricular fibrillation. 

During the flutter and fibrillation of the ventricles, the circulation stops, which is manifested by:
* loss of consciousness;
* stopping of breathing;
* disappearance of the pulse on large arteries;
* pallor of limbs and bluing of limbs;
* convulsions;
* biological death (occurs in 5-6 minutes, if urgent medical treatment is not performed).

Since flutter and fibrillation of the ventricles are extremely dangerous for life, treatment should be started as soon as possible. 

==Causes== 
In most patients, flutter and fibrillation of the ventricles develop due to various heart diseases, as well as non-cardiac diseases.
* [[Ischaemic heart disease]] (It is a disease caused by insufficient blood supply and oxygen supply to the heart), including [[myocardial infarction]] (death of heart tissue due to a violation of its blood supply).
* [[Arterial hypertension|Hypertension]] (It is a steady increase in blood pressure above 140/90 mm Hg).
* Myocarditis (It is affection (inflammation) of the heart muscle, which occurs most often because of an infectious disease).
* Heart defects (violation of heart structure)
* Cardiomyopathy (It is a disease in which there is a change in the structure and function of the heart muscle, the cause is most often unknown).
* Intoxication (poisoning) and side effects of certain medicines.
* The impact of electric current (electric shock, lightning).
* Hypothermia.
* Hypoxia (It is a lack of oxygen in the body tissues).
