When variable decelerations are associated with uterine contractions, their onset, depth, and duration commonly vary with successive uterine contractions. [citation needed] Prolonged deceleration: a decrease in FHR from baseline of at least 15 bpm, lasting at least 2 minutes but less than 10 minutes. A deceleration of at least 10 minutes is a ...
Histopathology of placenta with increased syncytial knotting of chorionic villi, with two knots pointed out. The following characteristics of placentas have been said to be associated with placental insufficiency, however all of them occur in normal healthy placentas and full term healthy births, so none of them can be used to accurately diagnose placental insufficiency: [citation needed]
Uterine Tachysystole is a condition of excessively frequent uterine contractions during pregnancy. [1] It is most often seen in induced or augmented labor, though it can also occur during spontaneous labor, [2] and this may result in fetal hypoxia and acidosis.
Fetal distress, also known as non-reassuring fetal status, is a condition during pregnancy or labor in which the fetus shows signs of inadequate oxygenation. [1] Due to its imprecision, the term "fetal distress" has fallen out of use in American obstetrics.
The sensory disorientation of returning from a prolonged banking turn to wings-level flight can cause the pilot to re-enter the banking turn, as in the graveyard spin illusion. While the plane continues in the turn and begins to indicate a loss of altitude, the pilot will try to correct the loss of altitude by "pulling up" on the plane's controls.
Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure.

In gerontology, late-life mortality deceleration is the disputed theory that hazard rate increases at a decreasing rate in late life rather than increasing exponentially as in the Gompertz law. Late-life mortality deceleration is a well-established phenomenon in insects, [ 1 ] which often spend much of their lives in a constant hazard rate ...
