Abstract
A system and method for pulse modulating a cardiac pacing signal provides a way to have the pulse modulation characteristics be descriptive of critical information relating to the operational performance of an implanted pacemaker. The patient's ECG/EKG signal is modulated by varying the pulse-intervals of a prescribed plurality of ventricular stimulation pulses in a manner descriptive of important pacer/patient information, such as Pacemaker Battery Status, Pacemaker Sensor Function, Impedance of the Atrial Lead, Impedance of the Ventricular Lead, Existence of Specified Rhythmic Conditions, Indicated Extrsystoles Rates, and other related parameters. The resulting pulse-modulated signal is suitable for transtelephonic transmission to remote locations for subsequent demodulation and analysis. The preferred method comprises the steps of determining or measuring parametric information for selected pacemaker parameters of the implanted pacemaker, varying the pulse characteristics (i.e. timing intervals) of the ventricular stimulation pulses generated by the implanted pacemaker to be descriptive of the parametric information for the selected pacemaker parameters, and triggering the generation of a prescribed plurality of ventricular stimulation pulses having such descriptive pulse characteristics.
