WebA body is said to vibrate when it describes an oscillating motion about a reference position. The number of times a complete motion cycle takes place during the period of a second is called the frequency and is measured in hertz (Hz). The motion can consist of a single component occurring at a single frequency, as with a tuning fork, or of ... WebAug 1, 1997 · Mean peak E′ velocity and peak A′ velocity were 10.0 ± 1.3 cm/s and 9.5 ± 1.5 cm/s, respectively, with an E′/A′ ratio of 1.1 ± 0.2. As with peak E and A velocity of mitral inflow, peak E′ velocity decreased and peak A′ velocity increased with age ( Table 1 ).
