Isovolumetric bladder contractions probably occurred during ongoing urgency to void, while bladder volume remained constant.
The authors observed that acute cigarette smoking caused a shift of mitral blood flow from early to late diastole and a prolongation of isovolumetric relaxation; they thereby concluded that cigarette smoking, by affecting LV filling and isovolumetric relaxation, significantly impaired LV diastolic function independently of its role as a risk factor for coronary atherosclerosis.
The peak early (E) and late (A) diastolic mitral inflow velocities, deceleration time E, E/A ratio and isovolumetric relaxation time were measured and averaged over 3 cardiac cycles according to the recommendations of the American Society of Echocardiography (30).
Deflation of the balloon occurs at the end of isovolumetric contraction (just before opening of the aortic valve) and is maintained the onset of diastole.
Preservation of parent rock fabric in saprolite due to in situ isovolumetric weathering (Nahon 1991) may be responsible for the higher values of dry and wet strength.
The characteristics of the different transvalvular flows and normal values for the lefi ventricle isovolumetric relaxation time (IVRT), the peak velocity (Vp) and ventricular ejection time (Tey) for the sigmoid valves flow, were also established.
Isovolumetric relaxation time and tissue Doppler e' (early diastolic tissue velocity) fell while the ratio of mitral inflow velocity E to e' rose with increasing BMI, suggesting depressed myocardial relaxation properties and increased left ventricular filling pressures.
O'Beirne-Ryan and Zentilli (2003) pointed out that many of these horizons no longer exhibit isovolumetric weathering and therefore are no longer "saprolites" senso stricto.
When protein is provided as a 50-g dose in the form of a beverage and compared with an isocaloric, isovolumetric and palatability-matched carbohydrate beverage, protein has also been shown to be more satiating than glucose.
001) and comparable accuracy in diagnosing mild left ventricular diastolic dysfunction [153 patients (60%) with altered relaxation, early-to-late phase ratio <1, deceleration time >220 ms, isovolumetric relaxation >110 ms] in stage B patients [BNP: AUC 0.
The sphering of platelets in EDTA is initially isovolumetric (16,17), but almost immediately, their apparent size changes over ~1-2 h until a state of semiequilibrium is reached (8, 17, 18).
