  • (20) Overall, measured isobaric diameters and measured compliance correlated with systolic, diastolic, and mean blood pressure values (p less than 0.001), whereas isobaric compliance correlated only with systolic (p less than 0.05) and pulse (p less than 0.01) pressure values.

Isochronic


Definition:

  • (a.) Isochronal.

Example Sentences:

  • (1) "Isochronic activation curves" for Ix and decay of current tails at -40 mV remained unaffected after Mn.
  • (2) DDS shifted current-voltage (I-V) and isochronal inactivation curves of ICa,L in the negative direction, whereas DDTMA shifted them in positive direction.
  • (3) Finally, the isochronal Emax and other end-systolic P-V relation slope values demonstrated inverse linear relationships with left ventricular mass (r = -.68 to -.91, p less than .05 to p less than .001).
  • (4) Adults hear alternating syllables with isochronous syllable onset-onset times as having a long-short, alternating rhythm when the syllables differ in initial consonant.
  • (5) Moreover, indirect P-V relations underestimate these Emax values, but they are linearly related with the isochronal Emax values calculated by RNA and CINE.
  • (6) When the standard pattern consisted of equally timed (isochronic) brief tones, whose interonset intervals (IOIs) were 50, 100, or 200 msec, the accuracy in detecting an asynchrony or deviation of one tone in the sequence was about as would be predicted from older research on the discrimination of single time intervals (6%-8% at an IOI of 200 msec, 11%-12% at an IOI of 100 msec, and almost 20% at an IOI of 50 msec).
  • (7) Isochronal data during early systole were better fitted to a parabolic than to the linear model; however, fits to linear and parabolic models were equally good near end of systole.
  • (8) The final positions of isochronically transplanted neurons in the host brain were mapped out by using the 3H-thymidine marker after long survival periods.
  • (9) The manuscript reviews evidence that these assumptions may not always be true, and when they are not, the isochronal map may be misleading.
  • (10) In addition, by using lines of constant analysis time (isochrons), it was found that several sets of conditions will result in nearly identical retention times.
  • (11) To investigate whether components of vector loops could provide information about different activation directions in local areas of myocardium, we correlated "instantaneous vectors" with isochronal activation patterns in an in vitro preparation of experimental myocardial infarction.
  • (12) Thus the sequence of morphological differentiation and the eventual laminar position of the isochronically transplanted neurons closely paralleled that of their normal host counterparts.
  • (13) In each case, the resolution equation, when written in terms of isochronal conditions, shows that improvements can be obtained without sacrificing analysis time.
