Abstract: Systems, computing platforms, and methods for sampling and analyzing common mode noise on electrocardiogram signals to help to minimize the interference to the electrocardiogram signals are disclosed. Exemplary implementations may: 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 to identify common mode interference levels within 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 identify sources of common mode interference.
