Ejection fraction is the most important indicator of heart failure. Angiography , is a standard method to demonstrate ejection fraction but it is invasive. Therefore determination of sensitivity and specificity of echocardiography versus angiography is a good guidance for physicians. A total number of 50 patients were enrolled in a prospective study. Two dimension and M-Mode echocardiography...
Objective- to determine the range of systolic times intervals using Pulsed-wave Doppler and m-mode echocardiography in normal, healthy Great Dane dogs. Design- Descriptive study. Animals- Thirty healthy Great Dane dogs. Procedures- This study examined 30 clinically healthy Great Dane dogs by the twodimensional, M-mode and Pulsed-wave Doppler echocardiography. The dogs were awake and unsedated. ...
Introduction: Patent ductus arteriosus (PDA) is the persistence of a normal fetal structure between left pulmonary artery and descending aorta. Persistence of this fetal structure beyond 10 days of life is considered abnormal. In this study we compared M-Mode and Doppler echocardiography in diagnosis of PDA in children at Aliasghar Hospital in Zahedan and Children hospital in Bandar Abbas for...
breed-wise standard echocardiographic values in dogs have been reported as there is variation in body and chest conformation which limits the application of data of one breed for other breed. labrador retrievers being originated from hunting dogs, might have different echocardiographic values from standard normal range of other dog breeds. so, the present study was aimed to determine the m-mode...
Echocardiography has been accepted as the diagnostic modality of choice for mitral valve prolapse (MVP). The determine the effect of position on echocardiographic diagnosis of MVP, we examined 693 consecutive patients referred to the echocardiography laboratory because of suspected MVP. First, patients were examined using the usual standard M-Mode echocardiography( left parasternal third or fou...
The accuracy of electrocardiography, M-mode echocardiography and two-dimensional echocardiography in predicting left ventricular hypertrophy was compared in 50 patients who came to autopsy within 6 months after the studies were performed. Several methods for determining left ventricular hypertrophy were examined for each of the three techniques. M-mode echocardiography was technically adequate ...
The slope of an individual contrast trajectory on M-mode contrast echocardiography represents a physiological variable similar to that measured by Doppler echocardiography: the projection of the intracardiac velocity vector in the direction of the sound beam. To test the hypothesis that M-mode contrast echocardiography slope measurement can yield information quantitatively similar to Doppler me...
