1. A system configured for sampling and analyzing common mode noise on electrocardiogram signals to help to minimize interference to the electrocardiogram signals, the system comprising:
one or more hardware processors configured by machine-readable instructions to:
obtain electrocardiogram signals from one or more sensors configured to be attached to a patient and communicatively connected to a patient monitor;
receive the electrocardiogram signals from one or more sensors by the patient monitor;
display the electrocardiogram signals on one or more displays of the patient monitor;
sample and analyze a direct current range and an alternating current spectrum using spectrum analysis to identify common mode interference levels in the obtained electrocardiogram signals;
display the direct current range and the alternating current spectrum via the one or more displays of the patient monitor; and
update the display of the direct current range and the alternating current spectrum in real time to help to identify sources of common mode interference.
