Gradient

Gradient (lat.gradiens, gradientis - moving, walking) is a quantity used in biology that reflects a quantitative change in any morphological or functional properties (including physicochemical) along one of the axes of an organ, body or cell.

  1. Decreasing gradient of automation - characterizes a decrease in the frequency of automatically appearing excitations of various zones of the heart towards the apex of the heart from its base;
  2. Pressure gradient in cardiology - represents the difference in blood pressure in any directly communicating two parts of the cardiovascular system;
  3. Metabolic gradient - characterizes the metabolic rate;
  4. Pulse amplitude gradient - displays the difference in the amplitudes of the systolic waves of the sphygmogram (pulse curve) recorded from two consecutive sections of the arterial bed; the study of the amplitude pulse gradient allows the bloodless method to establish the area of arterial lesion (aneurysm, narrowing, shunt, etc.), and also indirectly determine its degree;
  5. Temperature gradient in medicine - shows the difference between the body surface temperature and the temperature of internal organs;
  6. Physiological gradient - reflects a change in a physiological indicator.
