A system for analyzing cardiac waveforms is provided that allows a physician to accurately measure specific portions of a displayed IEGM or EKG signal. By examining the cardiac waveform with the analyzing system, the physician can quickly and accurately determine whether the device is operating properly. The physician may use one or two cursors or an icon or pointer to define a specific portion of the cardiac waveform to be analyzed. Various waveform characteristics such as relative waveform amplitude, maximum slew rate, power spectral density, and time elapsed can be determined for the specific portion of the cardiac waveform. If desired, the waveform characteristic determined for the specific portion of the cardiac waveform can be compared to statistical waveform data (e.g., in the form of a histogram).
