Ea ratio on echocardiogram
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, an … See more 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 … See more • 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 … 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 … 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) 3. Pseudonormal (E:A ratio appears normal) See more WebAug 23, 2024 · What is a normal mitral valve E A ratio? If relaxation of the myocardium is abnormal, not only the magnitude of e’ is decreased but also the time of opening of the mitral valve is delayed [8-10]. An E/e’ ratio < 8 is considered to be normal, and a ratio > 15 is considered to reflect an increase in the LV filling pressure [11-13].

"E" is the early filling of the left ventrical and entails about 70 to 75% normally without atrial contraction. "A" arises due to atrial contraction forcing approximately 20-25% of the blood into the LV. The peaks of each is an E and A wave.
