simple, triage and rapid treatment
It is a growth spurt.
slow
A rapid rate of change (which looks like this, U). A slow rate of change would have a slowly declining line like this (\ \ \ )
Wave summations, particularly in the context of muscle contractions, can theoretically continue as long as the muscle fibers are stimulated before they can fully relax. This leads to a cumulative effect where each successive stimulus adds to the previous ones, resulting in increased tension. However, in practical terms, there are physiological limits due to factors like fatigue and depletion of energy resources, which prevent indefinite summation. Thus, while wave summation can occur in rapid succession, it cannot go on infinitely in a biological system.
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).
Rapid but regular contractions are called tachysystole. This term is often used in the context of labor, referring to a situation where contractions occur more frequently than normal, typically defined as more than five contractions in a 10-minute period. Tachysystole can impact fetal well-being and may require medical intervention if it leads to distress.
Contraction Band Necrosis
These are characterized by rapid muscular contractions accompanied with jerks in facial and pelvic muscles.
fast Glycolytic
Premature ventricular contractions (PVCs) are extra heartbeats that originate in the ventricles, while atrial fibrillation (AFib) is an irregular and often rapid heart rhythm that originates in the atria. PVCs are usually harmless, while AFib can increase the risk of stroke and other complications.
