E/A ratio

The E/A ratio is a marker of the function of the left ventricle of the heart; it is determined on echocardiography, an ultrasound-based cardiac imaging modality. Abnormalities in the E/A ratio on Doppler echocardiography suggest that the left ventricle, which pumps blood into the circulation, cannot fill with blood properly in the period between contractions. This phenomenon is referred to as diastolic dysfunction and can eventually lead to the symptoms of heart failure. The E:A ratio is a first generation test for diastolic performance of the heart.
