Resting & Stress ECG with seca
ct330/331 and seca diagnostic 5.9
Monitoring and electrode control
The patient's ECG signal is displayed on the screen, but not yet
recorded (monitoring). Work steps before starting:
→ Change the type of Lead if necessary.
→ Check whether the electrodes are in optimal contact. If red lines are
visible on the screen, there is insufficient contact between the skin
and the electrode(s). The corresponding electrodes must be
reattached.
→ Set the desired Filters (Options menu ).

ECG filters limit the signal range and can suppress diagnostically
relevant portions of the ECG signal. Muscle filters (45 Hz) and
ergo
filters in particular reduce the transmission range of the ECG signal.
Information for the ECG analysis may be lost as a result.
Therefore, do not always switch on ECG filters, but only in specific cases
where an ECG filter is required.
