Fetal Doppler Echocardiography
Clinical Obstetrics and Gynecology, 1989Les auteurs rappellent les particularites du systeme cardiovasculaire fœtal et donnent les indications de son exploration par echographie Doppler. La technique de l'examen du cœur fœtal est ensuite decrite ainsi que les differents traces obtenus. Le chapitre se termine par les applications possibles de cet examen au diagnostic in utero des anomalies ...

Doppler echocardiography in adenotonsillar hypertrophy
International Journal of Pediatric Otorhinolaryngology, 2000Adenotonsillar hypertrophy causing upper airway obstruction may lead to the pulmonary hypertension and cor pulmonale. This study aimed to clarify the diagnostic methods of this complication, besides polysomnography, to find another objective criterion for surgical intervention and to demonstrate the curative effect of adenotonsillectomy on this ...

Gabor spectra for Doppler echocardiography [PDF]
Medical & Biological Engineering & Computing, 1998 Doppler echocardiography on current ultrasonography machines makes use of short-time Fourier spectrograms (STFTs) to display the patterns of blood velocities in the heart chamber. From these sonologists infer the functional parameters, such as valve area, that have pathological significance.

Doppler Echocardiography and Cardiac Pacing [PDF]
Pacing and Clinical Electrophysiology, 1982 There is a need for a non‐invasive method to evaluate the hemodynamic consequences of pacing. The value of Dop pler echocardiography in assessing relative changes in stroke volume and cardiac output is reviewed. We present preliminary observations illustrating the potential value of Doppler echocardiography in cardiac pacing. (PACE, Vol. 5, July‐August,

Doppler echocardiography in the human fetus
Journal of the American Society of Echocardiography, 1988Fetal echocardiography has allowed prenatal diagnosis of heart disease to become a reality over the last decade. Recently, pulsed Doppler flow studies have been applied to the examination of the fetal cardiovascular system. In fetuses with dysrhythmias, complex structural heart malformations, nonimmune hydrops fetalis, or mothers receiving nonsteroidal

Doppler echocardiography in shocked patients
Current Opinion in Critical Care, 2013To reiterate the necessity of integrating echocardiography in the management of shocked patients and to propose a step-by-step functional evaluation of hemodynamics proven to optimize hemodynamic monitoring and to adapt the treatment.Echocardiography has become the cornerstone to hemodynamic monitoring.

Exercise Doppler Echocardiography
Echocardiography, 1987SummaryDoppler echocardiography is a promising technique for evaluating left ventricular performance during exercise. The method is inexpensive and relatively simple to perform and analyze. Studies of reasonable quality can be performed even at high workloads.

Pulsed Doppler echocardiography
1977Cardiac ultrasound has greatly enhanced our ability to define structural disorders in the heart and great vessels. While certain cardiac diseases lend themselves to firm diagnosis by M-mode echocardiography, many valvular and congenital disorders result in normal or nonspecific echocardiographic findings.

Pulsed doppler fetal echocardiography
Journal of Clinical Ultrasound, 1985AbstractPulsed Doppler echocardiography (PDE) has proven value in the examination of the infant or child with known or suspected congenital heart disease. In order to assess how PDE might be useful in the evaluation of the infant in utero, we reviewed our experience with this technique used in combination with both cross‐sectional and M‐mode ...

Stress Doppler echocardiography
1989Perhaps the most serious intervention a cardiologist can recommend to patients under his care is cardiac surgery. Doppler ultrasound has proven merit in identifying patients with critical mitral and aortic stenosis, as well as severe aortic regurgitation who may warrant such intervention [1, 2, 3]. However, the most common complaint that patients bring
