Velocity of presystolic wave in LVOT has a positive colleration with A wave's velocity mesured in mitral valves level (rho = 0, 41, p <0, 01), a negative colleration with E / A ratio (rho=0, - 0, 244, p=0, 027) and a positive colleration with Tei index of the left ventricular (rho = 0, 345, p< 0, 05).
