simple, triage and rapid treatment
slow
It is a growth spurt.
A rapid rate of change (which looks like this, U). A slow rate of change would have a slowly declining line like this (\ \ \ )
A fast-flowing and turbulent part of the course of a river.
fibrillation
Ventricular fibrillation is the term for rapid irregular contractions of the ventricles. Because the contractions are unsynchronized and random, the ventricles do not pump effectively. The patient may have no palpable pulse, and the condition can be fatal.
Rapid and dangerously uncoordinated ventricular contractions is called ventricular fibrillation, or v-fib. During v-fib, the ventricle is not pumping blood to the body, and thus v-fib is known as a lethal dysrhythmia.
Atrial fibrillation is caused by rapid and irregular contractions of the atrial myocardium, leading to ineffective pumping of blood from the atria. This irregular heart rhythm can increase the risk of blood clots and other complications if left untreated. Treatment options may include medication, electrical cardioversion, or catheter ablation.
Fibrillation
The medical term for rapid but regular atrial or ventricular contractions is tachycardia.
"atrial fibrillation" is the irregular quivering action of the atria, which in turn, may cause "palpitations" (the awareness of an irregular heartbeat) and/or "tachycardia" (rapid heartbeat).
Contraction Band Necrosis
These are characterized by rapid muscular contractions accompanied with jerks in facial and pelvic muscles.
fast Glycolytic
Ventricular fibrillation is a rapid, irregular and uncoordinated contraction of the cardiac muscles.
Shivering is the rapid contraction and relaxation of muscles to generate heat.
