A real-time impedance monitoring system is provided for use with an implantable medical device having an implantable electrical lead. The impedance monitoring system includes components for determining the electrical impedance of the lead as a function of time, with the determination being made substantially in real-time, and components for graphically displaying the electrical impedance of the lead as a function of time, with the display also being generating substantially in real-time. In one specific example described herein, the implantable medical device is a pacemaker and the impedance monitoring system is within an external programmer device separate from the pacemaker. The programmer device includes a computer display screen or a computer printout device for presenting real-time graphical displays of the lead impedance. The programmer may alternatively generate graphical displays of lead impedance as a function of time based upon pre-recorded data.
