ECG AMP BOARD block diagram

The following is a block diagram of the ECG AMP BOARD.

The electrocardiographic signals input through the patient input connector
pass through the input protecting section to the differential amplifier, where
the right hand, left hand and chest 1 to chest 6 signals are subjected to
differential amplification with respect to the left leg signal. The outputs of
the differential amplifier are converted to digital signals by A-D converters.
Digitized electrocardiographic signals are transferred to the MAIN BOARD
by the AMP G/A. The ECG AMP BOARD block is electrically isolated by
photo-couplers and isolation power supply.
