Fibrillation

from Wikipedia, the free encyclopedia

Fibrillation describes spontaneous twitching of individual muscle fibers in the skeletal muscles. These twitches are invisible to the human eye.

In some diseases, uncontrolled small muscle fiber twitches can appear as a symptom . In the cardiology to "fibrillation" 'refers to rapid, irregular, and unsynchronized muscle contractions of the heart muscle , where it is a medical technical term from the English literature, less common in the Germans ( atrial fibrillation - atrial fibrillation , fibrillation ventricular - ventricular fibrillation ).

Demarcation

  • Fasciculation - short muscle bundle twitching visible under the skin without any movement effect
  • Myoclonia - muscle twitching with or without the effect of movement
  • Tremor - regular reciprocating motion (tremors)
  • Dystonia - prolonged muscle spasms
  • Myokymia - superficial, localized, wave-like muscle contraction

Plastics technology

In plastics technology , fibrillation describes the splitting off of thread-like fiber components largely parallel to the longitudinal axis of the fiber.
