Influence of Left Ventricular Diastolic Function on Blood flow Frequency Diagram of Pulmonary Veins / 中华超声影像学杂志

Pulse wave Doppler technique was used to detect the blood flow of pulmonary veins of 30 normal cases,50 patients with hypertension,heart disease,coronary heart disease,whose compensatory function of left atria are normal,and 20 patients suffering from bypertension,heart disease or coronary heart disease,whose function of left atria are deconpensated.The results showed that the systolic(s) and diastolic (D)heak velocities,atrial systolic(A),peaks and D/S ratio of the blood flow frequency diagram of pulmonary veins are new indexes to evaluate diastolic function of left ventricle.using the above barameters comprehensively,correct estimation of left ventricnlar diastolic function can be achieved.
