Table 2.
Fetal activity scores and mean (sd) fetal heart rate (FHRm) according to fetal activity
| Fetal activity | Score 0 | Score 1 | Score 2 | Score 3 |
|---|---|---|---|---|
| CONTROL* | 0 | 7 | 2 | 1 |
| HIGH-RISK* | 2 | 4 | 3 | 1 |
| CLONED* | 1 | 7 | 2 | 0 |
| Total | 3 | 18 | 7 | 2 |
| FHRm (bpm) | 39** +/− 67 | 115 +/− 12 | 120 +/− 8 | 123 +/− 2 |
The score of 0 was assigned to fetuses that did not move during the entire ultrasonographic examination, the score of 1 was given to fetuses that moved < 1/3 of the total examination time, the score of 2 was assigned to fetuses that were active < 2/3 but > 1/3 of the total examination time, the score of 3 was given to fetuses that moved for > 2/3 of the examination time.
There were no significant differences between the type of pregnancy and the activity score of the fetus (chi-squared test, P = 0.66).
Two of the 3 fetuses had no heart beat when their thorax was imaged. There was no association between the FHRm and the level of activity (P = 0.32) (fetuses with no activity were removed for the analysis).
