No ST events occured, T/QRS ratio was very stable and still normal variability. Physician on call decided to deliver with caesarean section because of tachycardia, maternal pyrexia and an Abnormal CTG trace > 60 min and no ST change. Abnormal CTG pattern for more than 60 min with normal ST requires qualified assessment.
Please observe the X:es are coming very close because of a higher Baseline Heart Rate. 30 heartbeats gives 1 X, equals 6 X:es if the baseline is 180 bpm.
