The Doppler Spectrum Normal Left Ventricular Long Axis Systolic Function and Its Clinical Application

Objective To evaluate the left ventricular Long-axis systolic rules using Doppler Tissue Imaging and to investigate its clinical value.Methods Totally 80 patients with coronary artery disease and 20 healthy volunteers were enrolled.Peak systolic velocity(Sm) were measured at mitral value in different left ventricular walls using Doppler Tissue Imaging.At the same time we analyse the dates we acquired to discuss the rules of the left ventricular Long-axis systolic.Results Through the comparison of Peak systolic velocity(Sm) we found that: LVIWLVLWLVAWIVS in the same healthy volunteer.Sm was reduced in the walls condition with coronary artery disease.Conclusions Pulsed Doppler Tissue Imaging can provide us a quantitative,direct and accurate method to assess left ventricular myocardial segment velocities.Pw-TDI is important in diagnosis of coronary heart disease.
