arrest (redirected from developmental arrest)

arrest /ar·rest/ (ah-rest´) cessation or stoppage, as of a function or a disease process.

---

cardiac arrest  sudden cessation of the pumping function of the heart with disappearance of arterial blood pressure, connoting either ventricular fibrillation or ventricular standstill.

developmental arrest  a temporary or permanent cessation of development.

epiphyseal arrest  premature interruption of longitudinal growth of bone by fusion of the epiphysis and diaphysis.

maturation arrest  interruption of the process of development, as of blood cells, before the final stage is reached.

sinus arrest  a pause in the normal cardiac rhythm due to a momentary failure of the sinus node to initiate an impulse, lasting for an interval that is not an exact multiple of the normal cardiac cycle.

sudden cessation or stoppage.

cardiac arrest

sudden and often unexpected stoppage of effective heart action. Either the periodic impulses which trigger the coordinated heart muscle contractions cease or ventricular fibrillation or flutter occurs in which the individual muscle fibers have a rapid irregular twitching.

epiphyseal arrest

premature arrest of the longitudinal growth of bone due to fusion of the epiphysis and diaphysis.

maturation arrest

interruption of the process of development, as of blood cells, before the final stage is reached.

sinoatrial arrest

a disturbance in cardiac conduction in which the sinoatrial node intermittently fails to generate an impulse. There are no P waves or PQRS-T complexes for at least twice the normal R-R interval. If the pauses are long enough, junctional or ventricular escape complexes may occur. Occurs most commonly in brachycephalic dogs, causing only minor clinical signs.
