NettetTwo distinct Doppler flow signals were detected in the left ventricular outflow tract during diastole. These were termed E' (early) and A' (active) because they occurred 40 to 100 ms after higher velocity mitral inflow E (passive filling) and A (atrial contraction) signals. http://www.pie.med.utoronto.ca/tee/TEE_content/TEE_spectral_lvot.html
