Webamplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. The amplitude of a pendulum is thus one-half the distance that the bob traverses in moving from one side to the other. Waves are generated by vibrating … WebDec 8, 2024 · Nonspecific ST-T-wave changes are very common and may be seen in any lead of the electrocardiogram. The changes may be seen in all or most of the leads (diffuse changes), or they may be present contiguous leads, such as the inferior, lateral, or anterior leads. The types of abnormalities are varied and include subtle straightening of the ST ...
WebA T-wave indicates the return of the ventricles from an excited state or relaxed state of ventricles. The sum of P and T-waves in a given time period corresponds to a specific electric activity of the heart. The end of a T wave marks the end of systole.
