1. An electrocardiogram (ECG) system comprising:
a drive-sense circuit (DSC) configured to:
generate a sensor signal based on a reference signal;
provide the sensor signal via an electrode that is coupled to an ECG lead and simultaneously to sense the sensor signal via the electrode to sense cardiac electrical activity of a cardiovascular system of a subject that is coupled from the subject into the ECG lead based on the ECG lead being in contact with a bodily portion of the subject;
adapt the sensor signal based on an error signal that is based on comparison of the reference signal to the sensor signal;
generate a digital signal that is representative of the cardiac electrical activity of the cardiovascular system of the subject that is sensed via the electrode that is coupled to the ECG lead based on the error signal;
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 electrode that is coupled to the ECG lead.
