| | Ventricular fibrillation - Wikipedia, the free encyclopedia |
 | | Subsequent to this in 1850, fibrillation was described by Ludwig and Hoffa when they demonstrated the provocation of Ventricular fibrillation in an animal by applying a "faradic" current to the heart [Hoffa M et al. | | | Researchers have looked at the frequency of the ventricular fibrillation waveform to see if it helps to elucidate the underlying mechanism of the arrhythmia or holds any clinically useful information. | | | Ventricular fibrillation has been described as "chaotic asynchronous fractionated activity of the heart" [Moe et al. |

| | Aortic valve replacement is associated with improved outcome in patients with hemodynamically significant valvular stenosis and well-preserved ventricular function. | | | Most patients with WPW syndrome and VF develop atrial fibrillation with a rapid ventricular response over the accessory pathway, which induces VF (see Image 3). | | | Coronary angiography: Perform cardiac catheterization in patients who survive VF to assess the state of ventricular function and the severity and extent of CAD. |

| | Resuscitation success places emphasis on early defibrillation, with the chance of survival inversely related to the duration of time between onset of ventricular fibrillation and the application of defibrillation(3). | | | This results in immediate loss of the pump action of the heart which leads to cessation of essential oxygen carrying blood flow to the body. | | | The second link is "early CPR", which can sustain a heart in ventricular fibrillation until personelle with medical equipment can arrive. |

| | One of the studies addressed in 2003 researched various clinical trials that implanted defibrillators into patients to prevent sudden cardiac death. | | | Research continues into methods to deliver defibrillation as soon as possible to those experiencing ventricular fibrillation. | | | After the heart resumes its normal rhythm, medications are given to help maintain the rhythm. |

| | Otherwise, drugs are given to prevent recurrences, or a defibrillator is surgically implanted to correct the problem, if it recurs, by delivering a shock. | | | Antiarrhythmic drugs may then be given to help maintain the normal heart rhythm. | | | If ventricular fibrillation is caused by a reversible disorder, that disorder is treated. |

| | VF is responsible for 75% to 85% of sudden deaths in persons with heart problems. | | | The person having VF suddenly collapses or falls unconscious, because the brain and muscles have stopped receiving blood from the heart. | | | Ventricular fibrillation is a medical emergency and should be treated immediately to preserve life. |

| | NEJM -- Ventricular fibrillation in the Wolff-Parkinson-White syndrome |
| | Patients with Wolff-Parkinson-White syndrome who are most susceptible to ventricular fibrillation have a history of atrial fibrillation and reciprocating tachycardia, demonstrate rapid conduction over an accessory pathway during atrial fibrillation and have multiple accessory pathways. | | | Guidelines for the management of patients with atrial fibrillation. | | | To examine the risk of ventricular fibrillation in patients with the Wolff-Parkinson-White syndrome, we compared patients who had this syndrome and a history of ventricular fibrillation related to preexcitation with patients who had the syndrome without this history. |

| | Collapse and sudden cardiac death will follow in minutes unless medical help is provided immediately. | | | Ventricular fibrillation (ven-TRIK'u-ler fib"rih-LA'shun) ("V fib") is a condition in which the heart's electrical activity becomes disordered. | | | If treated in time, V fib and ventricular tachycardia (ven-TRIK'u-ler tak"eh-KAR'de-ah) (extremely rapid heartbeat) can be converted into normal rhythm. |

| | Ventricular flutter (see figure 9B) with loss of consciousness and rapid unstable VT may be clinically equivalent to VF and is treated identically when accompanied by the clinical picture of cardiac arrest. | | | Ventricular fibrillation occurs commonly in the setting of acute ischemic events (see figure 70) or unpredictabley in advanced chronic ischemic heart disease. | | | Ventricular fibrillation may occur de novo, but among patients with out-of —hospital cardiac arrest, VT commonly precedes the onset of VF. |
