OverviewAI-generated
Ventricular fibrillation is a medical condition classified under the ICD-9-CM code 427.41. It is also identified by the NCI Thesaurus ID C50799 and corresponds to the ICD-10 name for the condition. The subject is associated with specific ontology identifiers, including HP_0001663 and SYMP_0000899.
Research on ventricular fibrillation is extensive, with 51,857 entries found in PubMed and 346 listings in ClinicalTrials.gov. The topic is widely documented, appearing in a Commons category and being referenced by 355 other encyclopedia articles.

Encyclopedic overview
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 can cause cardiac arrest and loss of consciousness without pulse. This is followed by sudden cardiac 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.
