Claim 20:
21. A method for sampling and analyzing electrocardiogram signals to enable filtering of common mode interference of the electrocardiogram signals, the method comprising:
obtaining electrocardiogram signals from one or more sensors configured to be attached to a patient and communicatively connected to a patient monitor;
receiving the electrocardiogram signals from one or more sensors by the patient monitor;
displaying the electrocardiogram signals on one or more displays of the patient monitor;
sampling and analyzing a direct current range and an alternating current spectrum using spectrum analysis to identify common mode interference levels in the obtained electrocardiogram signals;
displaying the direct current range and the alternating current spectrum via the one or more displays of the patient monitor; and
updating the display of the direct current range and the alternating current spectrum in real time to identify sources of common mode interference.
