A system determines electrical status of patient attached leads in medical patient monitoring. The system includes a repository of data indicating multiple predetermined impedance value ranges and corresponding associated lead status information of at least one electrical lead attached to a patient for conducting electrical signals for use in patient monitoring. An impedance measurement processor automatically successively determines whether an impedance value of a particular patient attached lead of multiple electrical leads attached to a patient is within a particular impedance value range of multiple predetermined impedance value ranges. An output processor automatically communicates data comprising a message identifying an electrical status of a particular lead of the multiple electrical leads by deriving status information from the repository in response to a determination the impedance value of the particular patient attached lead is within the particular impedance value range.
