PLUGSYS Einthoven Goldberger Module (EGM)
Used for capturing and amplifying ECG signals after Einthoven and Goldberger lead configuration, 6-lead ECG
The Einthoven Goldberger Module (EGM) is used for capturing and amplifying ECG signals after Einthoven and Goldberger lead configuration in the PLUGSYS system. It connects to 4 electrodes. This module has isolated input amplifiers in order to avoid hum interference.
Inputs Leads:
RA: Right Arm
LA: Left Arm
LF: Left Foot
RF Right Foot (Reference)
Output Signals: Bipolar Einthoven Extremity Leads:
I: LA(+) - RA(-)
II: LF(+) - RA(-)
III: LF(+) - LA(-)
Unipolar Goldberger Extremity Leads:
aVR RA(+) - (LA+LF)/2(-)
aVL LA(+) - (RA+LF)/2(-)
aVF LF(+) - (RA+LF)/2(-)
The 6 output voltages of the different leads can be switched through jumpers to the PLUGSYS system bus. From the system bus they can be picked off by a Recorder Output Module (ROM) for direct recording or a DAQ Hardware PLUGSYS for data acquisition by computer.
