(n.) A change in the letters or syllables of a word.
Example Sentences:
Systole
Definition:
(n.) The shortening of the long syllable.
(n.) The contraction of the heart and arteries by which the blood is forced onward and the circulation kept up; -- correlative to diastole.
Example Sentences:
(1) There was a weak relation between AER and both systolic and diastolic blood pressures.
(2) During control, no significant difference between systolic fluctuation (delta Pa) and pleural swings (delta Ppl) was found.
(3) The 40 degrees C heating induced an increase in systolic, diastolic, average and pulse pressure at rectal temperature raised to 40 degrees C. Further growth of the body temperature was accompanied by a decrease in the above parameters.
(4) Nicardipine lowered systolic and diastolic blood pressure to normal, plasma aldosterone was reduced and serum potassium levels were increased.
(5) Systolic blood pressure dropped following clonidine, showing a significantly greater drop for the medium and high doses than for the low dose.
(6) TR was classified as follows: severe (massive systolic opacification and persistence of the microbubbles in the IVC for at least 20 seconds); moderate (moderate systolic opacification lasting less than 20 seconds); mild (slight systolic opacification lasting less than 10 seconds); insignificant TR (sporadic appearance of the contrast medium into the IVC).
(7) A mean difference for individual patients between the first and second recording within 5 mm Hg was observed in 49.3% and 52.1% of patients for 24-hour systolic and diastolic blood pressure, respectively.
(8) Serial observations of blood pressure after unilateral adrenalectomy for aldosterone-producing adenoma revealed an incidence of hypotension (systolic BP less than fifth percentile for age- and sex-matched normal population) of 27% at 2 years, more than 5 times that predicted.
(9) In guinea pig ventricular myocytes, the positive contractile staircase was associated with ascending staircases of both peak systolic and end diastolic [Ca2+]i because of a cumulative increase in diastolic [Ca2+]i.
(10) Of great influence on the results of measurements are preparation and registration (warm-up-time, amplification, closeness of pressure-system, unhurt catheters), factors relating to equipment and methods (air-bubbles in pressure-system, damping by filters, continuous infusion of the micro-catheter, level of zero-pressure), factors which occur during intravital measurement (pressure-drop along the arteria pulmonalis, influence of normal breathing, great intrapleural pressure changes, pressure damping in the catheter by thrombosis and external disturbances) and last not least positive and negative acceleration forces, which influence the diastolic and systolic pulmonary artery pressure.
(11) Criteria for DOP administration were systolic blood pressure less than 100 mmHg and central venous pressure greater than 15 cmH2O.
(12) An excellent correlation was found between pulmonary artery systolic pressure measured by CW Doppler and catheterization (r = 0.98).
(13) At that time, blood pressures, systolic and diastolic left ventricular dimensions, indices of systolic function (% FS, mVcf) and exercise capacity had not changed, while cardiac output was decreased and systemic peripheral vascular resistance was significantly increased.
(14) Alterations in mean systolic blood pressure appeared to be modest, consisting of a 10 percent decrease from the control level, related to sedation, and a 10 percent rise from baseline during the procedure, associated with a concomitant mild tachycardia.
(15) With baseline measures and body mass index controlled for, analyses of covariance showed that adults had greater systolic blood pressure responses than did children; men had greater blood pressure responses to all stressors than did women; and high school boys had greater systolic blood pressure responses than did high school girls.
(16) Atrioventricular (AV) delay that results in maximum ventricular filling and physiological mechanisms that govern dependence of filling on timing of atrial systole were studied by combining computer experiments with experiments in the anesthetized dog instrumented to measure phasic mitral flow.
(17) Yet in 4 patients in whom no aortic late systolic pressure wave was apparent (group II), nitroprusside did not alter the difference between aortic and radial systolic pressures.
(18) YOH shifted the healthy subjects' mood towards feeling panicked, elevated systolic blood pressure and plasma prolactin concentrations, reduced digit symbol substitution, and induced drowsiness and passiveness.
(19) In order to study the vascular and adrenal renin angiotensin system in the chronic phase (4 months after clipping) of 'two-kidney, one-clip' hypertension in rats, systolic blood pressure, plasma renin activity, and tissue renin-like activity in both aorta and adrenal have been measured.
(20) Indirect methods to evaluate left ventricular function included the use of the Swan-Ganz catheter for pulmonary capillary wedge pressure measurement, systolic time intervals, and cardiac output.
