(11) The LV end-diastolic and end-systolic volumes (EDVI, ESVI), and ejection fraction in the subsequent cardiac cycle were calculated.
(12) The correlation coefficients between tests 1 and 2 were 0.92 for both the pre- and postexercise ejection fractions and 0.98 for both the pre- and postexercise wall motion scores.
(13) Combining these approaches, additionally including a low ejection fraction, subgroups of patients at very high risk of sudden death or sustained ventricular tachyarrhythmia can be identified.
(14) To validate the repeated use of radionuclide equilibrium angiography for determining left ventricular (LV) ejection fraction (EF) and end-diastolic and end-systolic volumes (EDV and ESV), 25 patients were studied on an hourly basis an average of 9.1 days after acute myocardial infarction.
(15) When an exercise test is not performed, a resting radionuclide left ventricular ejection fraction is recommended, and coronary angiography is considered if the value lies between 0.20 and 0.44 (12% 1-year mortality).
(16) It was concluded that 1) late ejection was quantitatively important to LV pumping, 2) behavior during late ejection was inconsistent with E(t)-R, and 3) ad hoc modification of E(t)-R models was not likely to yield LV pumping models that could satisfactorily reproduce instantaneous P(t) and Q(t) behavior over the entire ejection period.
(17) The results showed that the shortening fractions and ejection fractions were significantly depressed in the experimental embryos.
(18) Global left ventricular ejection fraction (LVEF) was obtained by radionuclide angiography and analyzed with an automatic detection program.
(19) Thus, patients are likely to live longer after CABG if they have left main disease; three-vessel disease with left ventricular dysfunction (ejection fraction less than 50%), class III or IV angina, provocable ischemia, or disease in the proximal left anterior descending coronary artery; two-vessel disease with proximal left anterior descending artery involvement; and two-vessel disease with class III or IV angina as well as either severe left ventricular dysfunction alone or moderate left ventricular dysfunction together with at least one proximal lesion.
(20) The maintenance of adequate blood circulation requires a sufficient ventricular contractility; in addition, to eject blood, the ventricles must first receive a sufficient volume, requiring a low diastolic stiffness.
Projectile
Definition:

Example Sentences:

(9) Asked to clarify Belmar’s remarks, Officer Brian Schellman, a spokesman for the county force, said in an email: “The Chief said we did not use rubber bullets, which are large rubber projectiles shot from the barrel of a firearm, which we did not use.
(10) (1) In sections showing no atherosclerotic changes, projectiles from hand weapons and from .22 calibre rimfire rifles leave remarkably small holes (comparable to the orifices of the intercostal arteries); in areas with sclerotic plaques the bullet holes are considerably larger.
