Quantitation of the motion of the cardiac base in the normal subjects by Doppler echocardiography
Using a noninvasive and readily available tool, transthoracic Doppler echocardiography
, aortic stiffness and coronary flow reserve can easily be simultaneous evaluated.
While standard pulsed-wave Doppler echocardiography
provides the temporal distribution of blood flow velocities in a specific location, color M-mode propagation velocity provides the spatiotemporal map of these velocities of the blood flow along the scan line from the mitral annulus to the left ventricle (LV) apex.
He had a left parasternal systolic murmur, produced by a ventricular septal defect, revealed by Doppler echocardiography
of fetal ductus arteriosus constriction versus increased right ventricular output.
uses similar ultrasound transducers and color-coded video to judge the speed, amount and direction of the blood cells flowing through parts of the heart and great vessels.
In those with normal cardiac function by Doppler echocardiography
, 32% had enlarged hearts.
TDI measures the walls of the heart, as opposed to conventional Doppler echocardiography
, which measures blood as it passes through the heart.
When we assess Doppler echocardiography
data we see mean TV A velocity of Group A pilots was significantly higher than those of Group B pilots.
For echocardiographic examination, a GE Vivid 7 Dimension (GE Vivid Ultrasound, Horten, Norway) Doppler echocardiography
unit was used.
NEW YORK -- A new way to visualize left ventricular dyssynchrony using Doppler echocardiography
may help identify patients with heart failure who would benefit from cardiac resynchronization therapy.
14) investigated the role of values recorded during the first stage of exercise Doppler echocardiography
in asymptomatic patients.
The women were examined with resting ECG, Doppler echocardiography
, and exercise stress testing, said Dr.
Marwick and other investigators have utilized tissue Doppler echocardiography
to demonstrate subtle systolic and diastolic dysfunction in asymptomatic type 2 diabetic patients with normal global systolic function and no coronary artery disease (J.
Color Doppler echocardiography
showed moderate mitral regurgitation, mild aortic valve insufficiency and subaortic membrane 10 mm below the aortic valve, which causes turbulent flow in the left ventricular outflow tract (LVOT).
