| fibrillation threshold | Least intensity of an electrical stimulus that will initiate fibrillation. (05 Mar 2000) |
|---|---|
| fibrillation, atrial | An abnormal irregular heart rhythm whereby electrical signals are generated chaotically throughout the upper chambers (atria) of the heart. Although many persons with atrial fibrillation have no symptoms, the most common symptom is palpitations, an uncomfortable awareness of the rapid and irregular heartbeat. Atrial fibrillation can cause blood clots that travel from the heart to the brain, causing stroke. Treatment of atrial fibrillation involves controlling the risk factors, medications to slow the heart rate and/or convert the heart to normal rhythm, and preventing complications of blood clotting. (12 Dec 1998) |
| fibrillation, auricular | Essentially the same as atrial fibrillation. (12 Dec 1998) |
| fibrillation, ventricular | An abnormal irregular heart rhythm whereby there are very rapid uncoordinated fluttering contractions of the lower chambers (ventricles) of the heart. Venticular fibrillation disrupts the synchrony between the heartbeat and the pulse beat. Ventricular fibrillation is commonly associated with heart attacks or scarring of the heart muscle from previous heart attack. Ventricular fibrillation is life threatening. (12 Dec 1998) |
| fibrillatory waves | The waves of atrial flutter usually best seen in ECG leads 2, 3, and AVF. (A small f indicates atrial fibrillation). Synonym: fibrillary waves, fibrillatory waves, flutter-fibrillation waves. (05 Mar 2000) |
| fibrillin | <protein> Widely distributed connective tissue protein (350 kD) associated with microfibrils (10nm diameter). (12 Nov 1997) |
| fibrilloflutter | Mixture of atrial flutter (FF) waves and fibrillation (ff) waves in the electrocardiogram. Synonym: fibrilloflutter, flutter-fibrillation. (05 Mar 2000) |
| fibrillogenesis | The development of fine fibrils (as seen with the electron microscope) normally present in collagenous fibres of connective tissue. (05 Mar 2000) |
| fibril |
Thin, solid strands in the cytoplasm of cells composed of protein and/or polysaccharide.

| fibrillae |
String-like elements that are loosened from the paper fibers during the beating process. They aid in the bonding processes when paper is being manufactured.
