An electrocardiogram (ECG) sensor system is disclosed that includes one or more interface connectors configured to be coupled to one or more electrodes. The ECG sensor system includes a processor configured to receive an ECG signal via the one or more interface connectors. The processor may be configured to determine one or more noise values associated with the ECG signal. Each of the one or more noise values may be indicative of a measurement of a component of the ECG signal that is potentially related to a non-heart beat source. The processor may be configured to send one or more noise values to an automated troubleshooting system.
