Ventricular fibrillation

Ventricular fibrillation is a severe, life-threatening cardiac arrhythmia and medical emergency affecting the cardiovascular system This lack of coordinated mechanical pumping results in an immediate cessation of effective cardiac output, precipitating hemodynamic collapse, loss of consciousness, and pulseless cardiac arrest Most commonly triggered by myocardial ischemia, structural heart disease, or underlying channelopathies, it leads to sudden cardiac death within minutes if not rapidly termi...

Ventricular fibrillation is a severe, life-threatening cardiac arrhythmia and medical emergency affecting the cardiovascular system It is characterized by rapid, highly disorganized electrical impulses within the ventricles, causing the myocardium to quiver erratically rather than contract synchronously This lack of coordinated mechanical pumping results in an immediate cessation of effective cardiac output, precipitating hemodynamic collapse, loss of consciousness, and pulseless cardiac arrest ...
