20Printing the ECG Waveform
FM30/50 You can print the ECG wave onto the trace paper. If you are monitoring both DECG and MECG,
both waves will be printed. The start of the wave recording is annotated above the wave with
MECG
for Maternal ECG, with
DECG for Direct fetal ECG, and with 25 mm/sec below the wave.
WARNING
The fetal/maternal monitor is not a diagnostic ECG device. In particular, the display of fetal/maternal
ECG is intended only for evaluating signal quality for fetal/maternal heart rate as derived from the
ECG waveform.
When in doubt, it can be used to identify sources of compromised signal quality, such as noise or
muscle artifacts. It can subsequently be used to verify the result of measures taken to resolve them
(e.g., checking ECG cable connections or adapting the fetal
ArtifactSuppress configuration).
The safety and effectiveness of the displayed fetal/maternal ECG waveform (i.e., P, QRS and T
segments) for evaluation of fetal/maternal cardiac status during labor have not been evaluated.
The ECG waveform is printed along the bottom of the heart rate grid, and the three different
possibilities look like this:
DECG waveform on its own
