Comment

This is a case with poor signal quality throughout the tracing with an odd ECG waveform. The T/QRS baseline is never determined and the ST information can therefore not be used for assessing the fetal state. The TOCO transducer is not applied properly, labour progresses very quickly and the patient delivers after only a few pushes.

Reminder

• Gaps in the T/QRS ratio >4 minutes may result in missed ST Events.
• Check for Event Log message ” Baseline T/QRS determined”
