Parallel Connection
To display traces on both PRM and ECG recorders using two different pa-
tient ECG leads, set up the equipment as shown in Figure 14.

2.
Connect the patient ECG cable to the patient electrode.

NOTE: This configuration will add the most noise to the tracings of the
two PRM–recorder configurations.
two PRM–recorder configurations.
4.
Adjust gain and filters on the external recorder.
Setup is now complete.
NOTE: The right leg electrode conductor on the patient ECG cable is a
driven ground. When connecting the PRM and an external ECG monitor
in parallel, the driven grounds for the two instruments must be connected
to the same patient limb (e.g. right leg electrode); otherwise, noise prob-
lems will occur.
