Pulsed Doppler echocardiographic evaluation of neonatal circulatory changes.
Pulsed Doppler echocardiograms were obtained from 42 normal fullterm neonates at less than 12 hours (20 subjects), 4 days (20 subjects), and 33 days (12 subjects). The acceleration time of the flow velocity and ventricular systolic time intervals were measured on recordings obtained at the right and left ventricular outflow tract, and the patency of the ductus arteriosus was evaluated by the fl...
متن کاملPulsed doppler echocardiographic study of mitral stenosis.
The value of pulsed Doppler echocardiography in the assessment of mitral stenosis was studied in a consecutive series of 175 patients before rightand left-heart catheterization. All Doppler recordings were interpreted independently by two observers. Twenty patients had repeat studies to demonstrate the reproducibility of the method. Adequate recordings were obtained in 156 patients. A normal fl...
متن کاملNormal pulsed wave Doppler echocardiographic parameters of Turkmen horses of Iran
Turkmen horse is one of the oldest and purest breeds in the world, but there is no information on Doppler echocardiographic parameters in this horse. In the present study, pulsed-wave (PW) Doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing Turkmen horses. No cardiac disease was detected with two-dimensional (2-D) real-time, M-mode, and colour flow mapping. D...
متن کاملPulsed doppler echocardiographic measurement of beat-to-beat changes in stroke volume in dogs.
Measurement of stroke volume by pulsed Doppler echocardiography has not been validated against a reference method in vivo. We compared Doppler systolic frequency shift integrals with electromagnetic flowmeter stroke volume in seven open-chest dogs. A pulsed Doppler echocardiographic transducer was held on the aortic arch with the sample volume in the ascending aorta. Stroke volume was varied by...
متن کاملPulsed Doppler echocardiographic determination of stroke volume and cardiac output
Two methods of measuring stroke volume and cardiac output with pulsed Doppler twodimensional echocardiography were developed and validated against the thermodilution technique in 39 patients, 33 of which were in an intensive care unit. With the use of the apical four-chamber view, a mitral inflow method combined the velocity of left ventricular inflow at the mitral anulus with the crosssectiona...
