Diastolic dysfunction measurements
WebApr 12, 2024 · Doppler echocardiographic measurements of diastolic dysfunction are dependent on preload, afterload, and sympathetic tone, which can vary on a daily basis. WebFeb 17, 2024 · A left ventricle (LV) ejection fraction of about 50% to 70% is categorized as normal. A mildly reduced LV ejection fraction is usually between 41% and 49%. A reduced LV ejection fraction is usually 40% or less. Even if you have a normal ejection fraction, your overall heart function may not be healthy.
