Patent ID: 8565863

Claim:
A method for acquiring ECG signals for an ECG monitor, the method comprising: forming a plurality of parallel measurement branches, each measurement branch comprising a protection resistor having a first terminal and a second terminal, wherein the first terminal is connectable to a respective ECG electrode to receive an electrode specific signal for the measurement branch; connecting, in each measurement branch, the second terminal of the protection resistor operatively to a first input amplifier; connecting, in each measurement branch, a first terminal of a capacitor operatively to a point between the second terminal and the first input amplifier; connecting, in each measurement branch, a second terminal of the capacitor to a virtual ground of a second input amplifier; and acquiring, in each measurement branch, an ECG channel signal from the first input amplifier and high frequency signals from the second input amplifier, wherein the ECG signal and the high frequency signal are acquired from the electrode signal for the measurement branch.
