Question: The following will be classified as a suspicious CTG
Base-line heart rate of 165 beats / minute with variability > 5 beats / minute and typical variable decelerations occurring with over 50% of contractions for 45 minutes
Correct answer: False
Baseline heart rate of 180 beats / minute with variability of 3 beats / minute for 30 minutes
Correct answer: False
The first one shows heart rate of 165 which is non- reassuring. The typical variable decelerations are only for 45 minutes & not > 90 minutes, so it is suspicious. Why the correct answer is false??
The second one shows heart beat 180 which is non-reassuring. The reduced variability for only 30 minutes& not for 40-90 as states by NICE, so it is suspicious & the correct answer is false.

Here is the definition of a suspicious CTG:
A CTG with one feature classified as non-reassuring and the remaining features classified as reassuring
Here are reassuring features:
Base-line 110-160, variability >/= 5 bpm, decelerations = none, accelerations may be present.
So look at the scenarios above and decide whether there is only one non-reassuring feature and all other features are reassuring. If not, the CTG is not suspicious and it is certainly not normal.
