1. Ventricular fibrillation

   Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. It is due to disorganized electrical activity. Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. This is followed by death in the absence of treatment. Ventricular fibrillation is initially found in about 10% of people with cardiac arrest.Ventricular fibrillation can occur due to coronary heart disease, valvular heart disease, cardiomyopathy, Brugada syndrome, long QT syndrome, electric shock, or intracranial hemorrhage. Diagnosis is by an electrocardiogram (ECG) showing irregular unformed QRS complexes without any clear P waves. An important differential diagnosis is torsades de pointes.Treatment is with cardiopulmonary resuscitation (CPR) and defibrillation. Biphasic defibrillation may be better than monophasic. The medication epinephrine or amiodarone may be given if initial treatments are not effective. Rates of survival among those who are out of hospital when the arrhythmia is detected is about 17% while in hospital it is about 46%.

1. ventricular fibrillation

   Ventricular fibrillation is a life-threatening cardiac condition characterized by a rapid and irregular heart rhythm. This condition causes the heart's lower chambers, called the ventricles, to quiver or fibrillate instead of contracting normally. As a result, the heart cannot pump blood efficiently to the rest of the body, leading to a lack of oxygen and nutrients to vital organs. Without immediate medical intervention, such as cardiopulmonary resuscitation (CPR) or defibrillation, ventricular fibrillation can lead to death. It is the most frequent cause of sudden cardiac death.

1. Ventricular fibrillation

   Ventricular fibrillation is a condition in which there is uncoordinated contraction of the cardiac muscle of the ventricles in the heart, making them quiver rather than contract properly. Ventricular fibrillation is the most commonly identified arrhythmia in cardiac arrest patients. While there is some activity, the lay person is usually unable to detect it by palpating the major pulse points of the carotid and femoral arteries. Such an arrhythmia is only confirmed by electrocardiography. Ventricular fibrillation is a medical emergency that requires prompt Advanced Life Support interventions. If this arrhythmia continues for more than a few seconds, it will likely degenerate further into asystole. This condition results in cardiogenic shock and cessation of effective blood circulation. As a consequence, sudden cardiac death will result in a matter of minutes. If the patient is not revived after a sufficient period, the patient could sustain irreversible brain damage and possibly become brain dead due to the effects of cerebral hypoxia. On the other hand, death often occurs if normal sinus rhythm is not restored within 90 seconds of the onset of VF, especially if it has degenerated further into asystole.

1. Ventricular Fibrillation

   A potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses (400-600/min) in HEART VENTRICLES. Such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness (SYNCOPE). It is one of the major electrocardiographic patterns seen with CARDIAC ARREST.
