Data analysis. We use a combination of two movement detection algorithms (23) written in Madab environment (The MathWorks, Inc.) to accurately track movement of the heart edges see Note 10). Measurements of diastolic and systolic diameters as well as diastolic and systolic intervals, % fractional shortening (% PS), arrhythmicity index, and contraction direction and velocity are obtained as output from this analysis program. Heart rate is calculated as the inverse of the heart period where one period corresponds to a single diastolic interval plus subsequent systolic interval. % FS is quantified based on diameter measurements and is calculated as ((diastolic diameter-systolic diameter)/diastolic diameter) x 100 (%). Heart beat rhythmicity is quantified based on the standard deviation of the mean heart period normalized to the median heart period for each fly providing a dimensionless arrhythmicity index. [Pg.243]

In a prospective study of ESRD at three Canadian centers, of the 518 patients who survived 6 months of dialysis, 74% had echocardiographic confirmation of LVH. Thirty-five percent had left ventricular dilation (LV cavity >90ml/m ) and 15% had systolic dysfunction (fractional shortening of less than or equal to 25%). LVH and dilation were independently associated with death at 2 years. [Pg.1697]

In the present studies, the parameters measured varied because of differences in hearf size, anatomy, species movement artifacts, and equipment used. However, certain parameters are constant across the studies, and these are used for comparative purposes. Two of these parameters (or surrogate) are also those used in the Common Terminology Criteria for Adverse Events (CTCAE), version 3 (v3), an adverse event rating, which is used for assessing adverse evenfs during clinical trials. These parameters include an assessment of left ventricular ejection fraction and fractional shortening of the left ventricle. [Pg.62]

It provides detailed information on cardiac structure (atrial and ventricular cavity dimensions, areas, volumes, wall thickness, and mass), cardiac function (systolic and diastolic, right and left ventricular wall motion, fractional shortening and ejection fraction, global and regional, and preload and afterload), valvular disease (structure, function, and degree of regurgitation or stenosis), vascular structures, and hemodynamic data. [Pg.203]

The mechanical cormected system is shown in Figure 2, which is used four dipole antennas. Each dipole antenna are using 2/A coaxial cable, actual length is decided by the fractional shortening of used cable and from 0.7 to 0.9. [Pg.126]
