Doppler mitral inflow recordings were considered inadequate if the angle between the echo beam and the mitral inflow was >30°., the sample volume was inadequately positioned, and the Doppler envelope was too indistinct to measure accurately.
Consideramos la imagen obtenida inadecuada caso el ángulo entre el haz de ultrasonido y el flujo transmitral fuera >30º, la muestra del Doppler pulsado estuviera mal posicionada, o la indefinición del envolvente del Doppler no permitiera mediciones precisas.
Consideramos a imagem obtida inadequada caso o ângulo entre o feixe de ultrassom e o fluxo transmitral fosse > 30Ú, a amostra do Doppler pulsátil estivesse mal posicionada ou a indefinição do envelope do Doppler não permitisse medidas precisas.
