E/a ratio and diastolic dysfunction
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 posterior to the ventricles, but for ease of understanding, are often drawn "above" … See more 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 … See more From this, a number of grades of diastolic function can be determined: 1. Normal diastolic function (E > A) 2. Impaired relaxation (E:A reversal i.e., E is < A) See more 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 ventricular hypertrophy, and with aging, the left ventricular wall can become stiff, … See more • Cursor position is important - if the PW sample window is incorrect, it produces artifact.
