First Claim
1. In an external programmer for use with an implantable cardiac stimulation device, a system for processing diagnostic information received from the stimulation device comprising:
- means for receiving location-specific event codes transmitted from the implantable cardiac stimulation device, with at least two of the distinct location-specific event codes being associated with the atria or with at least two of the distinct location-specific event codes being associated with the ventricles; and
means for generating graphic displays of location-specific event marker icons representative of the event codes, with a distinct location-specific event marker icon associated with each distinct location-specific event code.

Abstract
Location-specific diagnostic information is detected and recorded by the cardiac stimulation device for subsequent display using the external programmer device. The diagnostic information includes location-specific event records, counters and IEGM signals. The event records include event codes that distinguish among events occurring in the four chambers of the heart, such as sensed or paced events occurring within the left or right atria or the left or right ventricles. The counters separately count events occurring within the chambers of the heart. The IEGM signals are separately detected within the four chambers of the heart using a multiple sensing lead arrangement. The location-specific event records, counters and IEGM signals are ultimately transmitted to the external programmer, which displays graphic representations of the diagnostic information. The event records are displayed using distinct event marker icons which distinguish among the four chambers of the heart. The distinct event marker icons are displayed along with location-specific IEGM displays or surface ECG displays to permit a physician operating the programmer to easily identify the specific chambers of the heart in which events the occurred. Additionally, the programmer displays the values of the various counters to provide, for example, a set of location-specific histograms. The diagnostic information detected and recorded by the stimulation device and displayed by the external programmer device may further distinguish among events detected at multiple locations within each chamber of the heart. Method and apparatus embodiments are described.
