Exemplary external medical devices are configurable to communicate with an implantable medical device (IMD). One medical device includes multiple IMD telemetry ports operable to connect IMD telemetry mechanisms to the medical device. The medical device also includes a control unit configured to control the IMD telemetry mechanisms.

Systems and methods are provided for collecting enhanced diagnostic information specifically pertaining to overdrive pacing within an implantable cardiac stimulation device and for processing and displaying the enhanced diagnostic information using an external programmer. The enhanced diagnostic information includes one or more of overdrive pacing efficacy, overdrive pacing percentage, overdrive pacing/heart rate histogram data, longest recovery duration, atrial event data, minimum/maximum/average of the overdrive pacing rate, number of paced beats at maximum rate, duration of recovery time from maximum rate, intrinsic rate breakthrough histogram data, and number of rate increases. By tracking and displaying the enhanced diagnostic information, a physician can thereby more effectively and reliably program overdrive pacing control parameters to achieve optimal overdrive pacing performance.

Detecting and displaying diagnostic information pertaining to dynamic atrial overdrive pacing

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.

Event/rate data gathered by an implantable pacemaker is displayed in a histogram format as a function of heart rate and event type, with multiple events being included in the display of each rate bin of the histogram. Event types include a paced event, a sensed event, or a premature ventricular event (PVE). Two types of histograms are provided: (1) a heart rate histogram that shows the occurrence of each event type in each heart rate bin as a function of the percent of total events in all heart rate bins; and (2) a histogram that shows event type distribution by rate bin.

An implantable device programmer includes a variety of features for allowing a clinician to perform an automated and customized follow-up examination of a patient having an implanted cardiac implantable device, the implantable device being of the type which captures and stores various types of diagnostic data for subsequent retrieval and evaluation. A custom protocol feature of the programmer allows the clinician pre-specify and then semi-automatically follow an ordered sequence of protocol steps, each protocol step involving the interrogation of the implantable device and the display by the programmer of associated implantable device data (such as a heart rate histogram, or the results of a ventricular capture test). When the clinician initiates a custom protocol, the programmer automatically retrieves all of the diagnostic data records of the protocol in the protocol order. This automatic retrieval is performed in the background, allowing the clinician to begin viewing the initial diagnostic data records of the protocol while the other items are being retrieved. Via a user interface of the programmer, the clinician can rapidly and efficiently sequence through the data display screens associated with the protocol, to thereby view the various diagnostic data records and/or perform the various diagnostic tests of the protocol.

Methods and apparatus for identifying implantable cardiac devices are provided. Cardiac devices are classified as belonging to one of various device families, each of which may use a different communications protocol to communicate with an implantable cardiac device programmer. The family identification times anticipated for establishing a communications channel between the programmer and implantable cardiac devices in various device families are stored by the programmer. In addition, the programmer maintains a record of the implantable cardiac device families with which it has successfully communicated. The programmer identifies implantable cardiac devices based on the family identification time and record information, which reduces the amount of time necessary to complete family identification.
