| | Ventricular fibrillation - Wikipedia, the free encyclopedia |
 | | There are subsequently many theories about fibrillation in excitable media but it is only now with the increasing sophistication of experimental techniques that have become available that we can now try to study the complex spatial patterns that underlie sustained fibrillation. | | | However, fibrillation due to the administration of potassium and ouabain had a dominant frequency that was much slower at 4.8 Hz and 7.1 Hz respectively. | | | 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. |

| | For most patients, surgery for atrial fibrillation is elective. | | | Atrial fibrillation is very common in patients who require heart surgery for other reasons (mitral valve surgery, aortic valve surgery, coronary artery bypass grafting, and other surgical procedures). | | | During all surgical procedures to treat atrial fibrillation, the left atrial appendage is removed and the tissue is closed with a special stapling device. |

| | Effective clinical management of the patient with atrial fibrillation is based on evaluation of the patient's status, identification of appropriate medical goals, and determination of which specific therapies will be most effective in assisting the patient to reach the identified goal(s). | | | Until recently, no consensus about what therapy or combination of therapies is the most effective in the clinical management of atrial fibrillation existed. | | | Effective clinical management of the person with atrial fibrillation begins with a thorough history and assessment of the patient to identify the patient's type and pattern of atrial fibrillation. |

Yoshifumi Naka, MD and Mathew Williams, MD, who are trained in the most innovative treatment options for atrial fibrillation. | | | This technique is highly effective in curing atrial fibrillation. | | | We performed our first such closed chest, off-pump atrial fibrillation operation in February 2003, and we now offer this approach as a clinical option for treatment of lone atrial fibrillation. |

| | Cardiologist Dr. Richard Gray, medical director of the new Joint Cardiac Program of Marin General and San Francisco's California Pacific Medical Center, said, "Although many treatments for atrial fibrillation are offered, they are often ineffective and not long lasting. | | | Atrial fibrillation treatment sometimes also includes the implantation of pacemakers after ablation (localized disruption of electrical pathways in the heart). | | | Usually the next step in the treatment process is cardioversion - a low voltage shock to the chest wall to restore the heart's normal rhythm - but even this has to be repeated and eventually stops working. |

| | Loftus was a principal investigator for a study comparing warfarin to Exanta ® (Ximelagatran) for the prevention of stroke in chronic atrial fibrillation. | | | The association of stroke with atrial fibrillation has been known since 1658. | | | Currently, strokes are best prevented by the careful use of Coumadin® or warfarin. |

| | Hospital Practice: Cardiac Arrhythmia |
| | The only patients who do not require long-term drug therapy for rate control are those in whom atrial fibrillation develops after cardiac surgery. | | | Since disruption of normal atrial blood flow with stasis can promote thrombus formation, leading to stroke or peripheral embolization, first-line therapy for patients with atrial fibrillation is anticoagulation. | | | In those who have had a myocardial infarction, a beta-blocker would be the drug of choice, especially when the patient has left ventricular dysfunction. |

| | Encyclopedia4U - Ventricular fibrillation - Encyclopedia Article |
| | Ventricular fibrillation is a cardiac condition which consists of a lack of coordination of the contraction of the muscle tissue of the large chambers of the heart. | | | The ventricular muscle twitches randomly, rather than contracting in unison, and so the ventricles fail to pump blood into the arteries. | | | Ventricular fibrillation is one cause of cardiac arrest. |

| | Atrial Flutter |
| | Signs and symptoms often experienced with atrial flutter are similar to those of atrial fibrillation, such as a pounding heart rate or pulse, shortness of breath, or dizziness. | | | This rapid, irregular pattern gives rise to the symptoms of atrial fibrillation, such as palpitations, rapid heart beat, chest discomfort, shortness of breath and dizziness. | | | Contributing to the symptoms is the failure of the atria and the ventricles to have coordinated pumping action as they do in the normal situation, which can also lead to a less efficient cardiac pump. |

| | Ventricular fibrillation (ven-TRIK'u-ler fib"rih-LA'shun) ("V fib") is a condition in which the heart's electrical activity becomes disordered. | | | The heart beats when electrical signals move through it. | | | When this happens, the heart's lower (pumping) chambers contract in a rapid, unsynchronized way. |
