Chez les patients présentant une fibrillation auriculaire, des anticoagulants sont souvent prescrits pour prévenir une embolie périphérique, surtout en présence d'une sténose mitrale. [8] Fibrillations can occur in healthy individuals. Precipitating factors should be sought and treated (for long-term management issues, see the section on sudden cardiac death, below). La sélection de telle ou telle médication est fonction du type de trouble du rythme. 2. the quality of being made up of fibrils. These alterations and slow rhythmic oscillations in the resting potential or isolated local depolarizations result in subthreshold depolarizations in the resting membrane potential that produce a spontaneous, regularly firing action potential (Li et al., 1957; Buchthal and Rosenfalck, 1966; Purves and Sakman, 1974; Desmedt, 1978). 1 : an act or process of forming fibers or fibrils. The lumbar paraspinal muscle examination has been refined through investigations that used a grading scale for the findings.37–40 The ‘mini PM’ score provides a quantitative means of deriving the degree of paraspinal muscle denervation.40 It distinguishes normal findings from persons with radiculopathy. Read medical definition of Fibrillation. ventricular fibrillation Definitions. fibrillation definition: 1. irregular, rapid contractions of muscles, especially the heart: 2. irregular, rapid…. Fibrillation may sometimes be used after heart surgery to stop the heart from beating while any minor leaks are stitched up. Such people include those in whom the atrial fibrillation or atrial flutter causes heart failure or other symptoms of low heart output. There are two major classes of cardiac fibrillation: atrial fibrillation and ventricular fibrillation. n. 1. Similarly, occasionally a fibrillation potential demonstrated a sudden change in the discharge frequency or blocking of firing (Conrad et al., 1972). en.wiktionary.org. Recruitment findings and motor unit morphology for these muscles has not been established and consequently we do not know for sure what constitutes normal. Patients are younger than the typical patient with degenerative joint disease (55 versus 67 years) and often have predisposing conditions such as steroid use, sickle cell disease, or alcoholism. Medical Definition of Fibrillation Medical Author: William C. Shiel Jr., MD, FACP, FACR Fibrillation : In cardiology, an abnormal and erratic twitching of the heart muscle. The forming of fibers. See also: Cardiology. What does fibrillation mean? en.wiktionary.org (pathology) Condition where the cardiac muscle is contracted irregularly and rapidly. Atrial fibrillation can be a chronic condition, usually treated with anticoagulation and sometimes with conversion to normal sinus rhythm. Fractures through articular bone result in subchondral cysts and collapse of the bone. Classe 3 : il s'agit d'agents qui prolongent la repolarisation et qui diminuent l'automaticité. Atrial fibrillation results in rapid and irregular heart and pulse rate. Primary Meanings of fibrillation. (noun) Dictionary ! muscle fibrillation causes A 59-year-old male asked: Can the flow rate on a IV line cause atrial fribulation, which in turn weaken the heart muscle, create clots and flood the lungs. translation and definition "ventricular fibrillation", Dictionary English-English online. In ventricular fibrillation, the … Patients usually undergo arthroplasty after significant secondary degenerative changes have occurred. Additionally, an effect of nerve degradation products in the axons, a reduction in factors carried to the nerve terminal for acetylcholine production due to disturbed axonal transport, and hypersensitivity of the postsynaptic acetylcholine receptors to acetylcholine following denervation may all play a role (Luco and Eyzaguirre, 1955; Axelsson and Thesleff, 1959; Goodgold and Eberstein, 1967; Cangiano, 1973; Cangiano et al., 1984; Arancio et al., 1989). Description of Benign Muscular Fibrillation. They found many irregularly firing potentials with similar waveform characteristics as fibrillations and positive sharp waves (PSW).
