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.

Abstract: A patient monitoring system includes a patient monitor and an ECG lead set coupled thereto. The patient monitor may be programmed to periodically issue interrogation signals to the ECG lead set to determine the type and connection status of the ECG lead set. The interrogation signals may be issued via a communication bus. The patient monitor may time the issuance of interrogation signals to the ECG lead set to correspond to non-critical ECG intervals, such that interference with the ECG signals by the communication bus is minimized.

Abstract: An ECG monitoring method and apparatus are presented in which contact impedances including capacitive components are utilized to, for example, reduce false alarms for lead-off conditions. In one aspect of the disclosure a method includes monitoring a plurality of Electrocardiogram (“ECG”) electrodes ostensibly electrically connected to a human body; determining the respective contact impedance for each of the ECG electrodes as a plurality of electrical currents is driven through the ECG electrodes in a predetermined pattern, each respective contact impedance including a resistive component and a capacitive component; ascertaining whether any of the determined respective contact impedances exceeds a predetermined threshold; if any of the determined respective contact impedances exceeds the predetermined threshold, issuing an alarm.

Abstract: Systems and methods are provided herein for monitoring electrocardiogram (ECG) electrodes. Each ECG electrode is electrically connected to a patient body and a corresponding current source. A reference ECG electrode of the monitored ECG electrodes is selected. Current is injected into each electrode. Each current has a respective predetermined level. Based on the injected currents, ECG electrode voltages are generated. The injected currents are adjusted after measuring the ECG electrode voltages while the predetermined level through the reference ECG electrode is maintained. An impedance associated with each non-reference ECG electrode is determined based on the ECG electrode voltage and the injected current.
