The E/A ratio is a marker of the function of the left ventricle of the heart. It represents the ratio of peak velocity blood flow from left ventricular relaxation in early diastole (the E wave) to peak velocity flow in late diastole caused by atrial contraction (the A wave). It is calculated using Doppler echocardiography, … Skatīt vairāk The heart is a biological pump designed to move blood through the brain and body. It has four chambers: two "upper" chambers called the atria, and two "lower" chambers called the ventricles. Anatomically, the atria are more … Skatīt vairāk • Cursor position is important - if the PW sample window is incorrect, it produces artifact. The cursor should be placed at the level of the open … Skatīt vairāk The E/A ratio is the ratio of the early (E) to late (A) ventricular filling velocities. In a healthy heart, the E velocity is greater than the A velocity. In certain conditions, especially … Skatīt vairāk From this, a number of grades of diastolic function can be determined: 1. Normal diastolic function (E > A) 2.
