  • regional myocardial
  • Although regional EF and strain imaging, as compared with wall thickening, enhance detection of improvement in complex measures of regional myocardial function, it remains unclear whether such measures are better able to predict meaningful improvement in clinical outcomes. (onlinejacc.org)
  • Transmural
  • In addition, contraction duration was longer in the subendocardium than in the midmyocardium, indicating a pronounced transmural mechanical dispersion that was not present in asymptomatic and healthy individuals. (ahajournals.org)
  • Contractile
  • After 45 min of equilibration at 37 degrees C or 32 degrees C, resting and action potentials, time to peak contraction and contractile force were recorded during pacing with a frequency of 60/min. (lu.se)
  • 0.05) increased the contractile force and membrane action potential duration at 50% and 90% repolarization levels both in normothermia and in hypothermia, whereas the duration of the contraction was not significantly changed. (lu.se)
  • atrial
  • The pattern of left ventricular diastolic filling changed, with a decrease of early peak flow (231 +/- 20 versus 217 +/- 21 mL/s, P = .022), of deceleration time (163 +/- 28 versus 116 +/- 26 seconds, P = .001), and of flow area during rapid filling (105 +/- 15 versus 75 +/- 12 mL, P = .004) and an increase of flow area during atrial contraction (39 +/- 4 versus 88 +/- 9 mL, P = .001).

  • cyclic
  • In the isolated perfused guinea-pig heart, the increases in isotonic contraction and in cyclic AMP, produced by 2 μg of histamine were significantly and almost completely inhibited in the presence of 2 mg of burimamide, whereas the adrenergic β-receptor blocking drug Kö 592 (50 μg) was ineffective.

  • noninvasive
  • Regional LV assessment is traditionally performed with qualitative or quantitative analysis of wall thickening within 16 myocardial segments, but advances in noninvasive imaging permit an increasingly more detailed and accurate evaluation of LV function. (onlinejacc.org)
  • Depression
  • The effects of inhalational anesthetic agents on myocardial contraction have been the focus of extensive investigations for many years, and the depression of force development by different inhalational agents has been repeatedly shown. (aspetjournals.org)
  • severe
  • BACKGROUND: Dynamic cardiomyoplasty is a relatively new surgical procedure proposed for treatment of severe myocardial failure. (mendeley.com)
