When the A-A interval became equal to the pacing cycle length after some beats of VOD, the cycle was considered the first entrained cycle and the H-H interval preceding the A-A interval was measured.
Averages for correct responses were computed relative to the 100 ms interval preceding the display onset, separately for each condition.
In order to determine the dynamics of QT interval, analyzing just RR interval preceding QT interval may be inadequate.
The median ACR measurement in the 2-year interval preceding enrollment was the baseline value.
(E ) Standard deviation of the current in the time interval preceding each flash.
Set A (nine S intervals, trailed by an increasing number of C intervals), and Set B (one trailing C interval, preceded by an increasing number of S intervals).
The topographical distribution of ERPs during an interval of 500 ms after S1-onset, 5 s of the retention interval, a 500 ms-interval preceding the S2, and a 1 s postimperative interval were evaluated.
Baseline activities were characterized by computing the average firing rates during time intervals preceding the startle stimuli.
Heart rate was calculated from three RR intervals preceding the measured QT intervals.
The show lasts an hour-and-a-half but there is a substantial interval and a great deal of overture.
There were four sequential conditions: (a) 9 leading S intervals followed by 1, 2, …, or 9 C-intervals; (b) 9 leading C intervals followed by 1, 2, …, or 9 S intervals; (c) 9 trailing C-intervals preceded by 1, 2, …, or 9 S-intervals; and (d) 9 trailing S-intervals preceded by 1, 2, …, or 9 C-intervals.
