Figure 1 Flow propagation velocity (Vp) was determined as the slope (yellow line) of the isovelocity line from the mitral plane to 4 cm apically into the left ventricle. Top left: Color M-mode recording of LV inflow from a normal subject. Bottom left: Pulsed wave Doppler signal of normal transmitral flow. E/Vp in this control was 0.99. Top right: Color M-mode recording from a patient with anterior MI and decreased Vp but normal appearing pulsed wave Doppler signal of LV mitral inflow (Bottom right). E/Vp in this patient was 2.1. E: peak E-wave velocity.
