A system and method for ECG electrode and leadwire connection integrity detection are provided herein. The system includes a plurality of electrodes wherein a uniform spectral energy signal is to be injected into a subset of electrodes of the plurality of electrodes. The system also includes a computing device. The computing device includes a display, and the computing device is communicably coupled to the plurality of electrodes. The computing device is configured to acquire input signals from an electrode and determine a frequency response from the electrode based on the input signal from the electrode. The computing device is also configured to determine impairments in the electrode and leadwire connection using the frequency response.
