1. A pacemaker system comprising:
a drive-sense circuit (DSC) operably coupled to a pacemaker lead, wherein, when enabled, the DSC configured to:
generate a pace signal including electrical impulses based on a reference signal;
provide the pace signal, via the pacemaker lead, to an electrically responsive portion of a cardiac conductive system of a subject to facilitate cardiac operation of a cardiovascular system of the subject and simultaneously to sense, via the pacemaker lead, cardiac electrical activity of the cardiovascular system of the subject including during delivery of the electrical impulses of the pace signal, wherein muscles of a heart of the subject produce a mechanical response to the electrical impulses of the pace signal to move blood through the cardiovascular system of the subject;
generate a digital signal that is representative of the cardiac electrical activity of the cardiovascular system of the subject that is sensed via the pacemaker lead;
memory that stores operational instructions; and
one or more processing modules operably coupled to the DSC and the memory, wherein, when enabled, the one or more processing modules is configured to execute the operational instructions to process the digital signal generated by the DSC to determine the cardiac electrical activity of the cardiovascular system of the subject that is sensed via the pacemaker lead.
