Claim 11:
12. The pacemaker system of claim 1, wherein the DSC further comprises:
a power source circuit operably coupled via a single line to the pacemaker lead, wherein, when enabled, the power source circuit is configured to provide an analog signal via the single line coupling to the pacemaker lead, and wherein the analog signal includes at least one of a DC (direct current) component or an oscillating component; and
a power source change detection circuit operably coupled to the power source circuit, wherein, when enabled, the power source change detection circuit is configured to:
detect an effect on the analog signal that is based on at least one of an electrical characteristic of the pacemaker lead or the cardiac electrical activity of the cardiovascular system of the subject that is sensed via the pacemaker lead; and
generate the digital signal that is representative of the cardiac electrical activity of the cardiovascular system of the subject that is sensed via the pacemaker lead.
