two-dimensional echocardiography การใช้

• Monitoring analysis on a rabbit model with acute pulmonary hypertension by two - dimensional echocardiography
• Conventional two - dimensional echocardiography ( 2de ) provides a limited view of the lv and makes assumptions about its shape that may cause error in studying abnormal ventricles . three - dimensional echocardiography ( 3de ) can offer more diagnosing information than 2de , allow to view 3d lv from any position and orientation and be more accurate and reproducible than 2de in measuring lv volume , mass and ejection performance by avoiding geometric assumption
• New methods for noninvasively detecting pulmonary pressure and left ventricular end - diastolic pressure manometer that measures megative pressure in mmhg was connected with the examined subject through a mask . the manometer is a remodeled sphygmomanometer for routine peripheral arterial blood pressure measurement that is market - available . the examined subjects were asked to carry out muller maneuver slowly so that the intrathoracic pressure decreases gradually while the blood flow of the right ventricular outflow tract observed with pulsed doppler echocardiography at the parasternal short - axis view of the great vessels in the two - dimensional echocardiography
