Web1 de ago. de 1997 · In our normal volunteers peak E′ velocity was higher than peak A′ velocity, mimicking the pattern of normal mitral inflow. However, reversal of the E/A ratio in mitral inflow occurred in subjects in their 60s whereas reversal of the E′/A′ ratio occurred in subjects in their 40s, a younger age group, thus supporting the preceding assumption.

Web23 de mar. de 2024 · atrial reversal velocity and duration. normally the peak of the AR wave is < 35 cm/s. a peak velocity exceeding this upper limit implies elevated filling pressures. the AR wave duration is typically examined in concert with the mitral inflow velocities. the transmitral A wave and the pulmonary venous AR wave should be roughly similar in length.
