A Comparative Study of Two-dimensional Echocardiography and Systolic Time Intervals in the Evaluation of Left Ventricular Function in Coronary Heart Disease
Eoaluation of the Two Dimensional Echocardiography Combining with Clinical and X-ray Analysis in Diagnosis of Interatrial or Interventricular Septal Defects
Between 1983 and 1985, 14 cases of IASAn were diagnosed by 2-Dimensional Echocardiography (2DE) performed in 6000 patients(0.23%) . During 2DE, the aneurysm appeared as a localised bulging of the IAS,which was seen in the four chamber apical view and in the subcostal four chamber view.
Among 368 people aged 50 and than 50 years, aortic valve calcification (AVC) was detected by 2-dimensional echocardiography in 92 people( 25.0% ), the incidence of AVC was increasing with the aging process.
Objective To assess the color kinesis(CK) ultrasonographic features and advantage in dobutamine stress echocardiographic test(DSE),comparing to 2-dimensional echocardiography(2DE).
METHODS:The apical four chamber view of 8 athletes under endurance training and 8 without training were recorded with two dimensional echocardiogram at rest,during exercise, and the end of 1 min,2 min,3 min after exercise ,and were analyzed later.
Conclusions:transabdomen ultrasonic diagnosis of pericardial effusion has the same value as Two Dimensional Echocardiogram,and is more effective in the diagnosis of pericardial effusion caused by tumor.
The study applied PHILIPS7500 two dimensional echocardiogram system to measure the sizes of patients,four cardiac chambers half year before and half year after the implantation respectively,and analyzed and compared the data from this duration.
Objective:To investigate the possibility of screening for fetal congenital heart diseases with Two Dimensional Echocardiogram extensively and its clinical value.
Conclusion: Assessment of regional long axis function by tissue Doppler echocardiography may yield important additional findings even if two-dimensional echocardiography is apparently normal.
Quantification of left ventricular volumes using conventional two-dimensional echocardiography is only possible when simplifying assumptions of left ventricular geometry are made.
Transpulmonary echo contrast agents improve the evaluation of left ventricular function by two-dimensional echocardiography due to a better endocardial border delineation.
