It is measured by recording the rate at which red blood cells (RBCs) sediment in a tube over time. It increases (the RBCs sediment faster) with more inflam...
  2. Rate, fetal mortality Rate, fetal mortality
    Rate, fetal mortality: The ratio of fetal deaths divided by the sum of the births (the live births + the fetal deaths) in that year. In the United States, the fetal mortality rate plummeted from 19.2 per 1,000 births in 1950 to 9.2 per 1,000 births in 1980. ...
  3. Rate, heart Rate, heart
    Rate, heart: Number of heart beats per minute. The normal resting adult heart beats regularly at an average rate of 60 times per minute. (Young children's hearts beat faster). The speed of the heartbeat (heart rate) is governed by the speed of electrical signals from the pacemaker of the heart, the ...
  4. Rate, infant mortality Rate, infant mortality
