Web14 de mar. de 2014 · Doppler Echocardiographic Data. The diagnosis of constrictive pericarditis was associated with greater respiration-related change in mitral E velocity (30.7±20.4% versus 13.7±17.0%; P <0.001; Figure 2) and a marginally greater ratio of deceleration time in expiration versus inspiration ( P =0.06). 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 ultrasound-based cardiac imaging modality. Abnormalities in the E/A ratio suggest that the left ventricle, which pumps blood into the systemic circulation, cannot f…
