Study of Cardiac Parameters by Pulsed Wave Doppler Echocardiography in Normal Healthy Markhoz Goat
Objective- The aim of this study was to test the repeatability, the variability, and to establish the reference values of PW measurements in healthy Markhoz goats.Design- Retrospective study.Animals- 20 female Markhoz goats.Procedure- Using a standardized PW Doppler echocardiographic protocol, 20healthy adult unsedated female Markhoz goats were investigated three times at one-...
متن کاملPulsed Wave Doppler and Color Flow Doppler Evaluation in Healthy Dogs and Dogs with Cardiac Disease
Doppler echocardiography gives a physiological assessment of blood flow within the cardiac chambers, across valve orifices and in the great vessels. Pulsed wave Doppler can detect flow pattern in a very discrete region of simultaneously imaged 2-D echocardiographic plane. Twenty apparently healthy dogs and twenty affected dogs with dilated cardiomyopathy and mitral valve insufficiency ten each ...
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 کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Cardiac dysfunction in acromegaly: evidence by pulsed wave tissue Doppler imaging.
OBJECTIVE To verify whether the accuracy of data on myocardial function provided by pulsed-wave tissue Doppler imaging (PWTDI), a new echocardiographic application that allows quantitative measurements of myocardial wall velocities, could help towards a better understanding of the natural history of acromegalic cardiomyopathy. DESIGN Eighteen patients with active acromegaly (ten men and eight...
