Dizziness and slow heart rate during exercise
The ECG at presentation shows an irregular baseline and no P-waves, suggesting atrial fibrillation. A regular multiform ventricular bigeminy with fixed coupling interval can be appreciated, which could be typically seen in digitalis intoxication [1]. Other potential ECG features of digitalis intoxication include decreased AV conduction (because of increased vagal effects on the AV node), possib...
متن کاملHead tilt during driving.
In order to distinguish between the use of visual and gravito-inertial force reference frames, the head tilt of drivers and passengers were measured as they went around corners at various speeds. The visual curvature of the corners were thus dissociated from the magnitude of the centripetal forces (0.30-0.77 g). Drivers' head tilts were highly correlated with the visually-available estimate of ...

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Evaluating dizziness.
PURPOSE To conduct a structured literature synthesis on the etiology, prognosis, and diagnostic evaluation of dizziness, and to suggest a primary-care approach to evaluating this symptom. METHODS Studies were identified from MEDLINE searches (1966 through 1996) and a manual search of bibliographies from retrieved articles. Two investigators independently abstracted study data. RESULTS The m...
