  • Patent number: 6941167
    Abstract: Systems and methods are provided for displaying statistical distributions of cardiac events. According to one aspect, a programmer device is provided that generally comprises circuitry for communicating with a medical device, and a display. The medical device collects data regarding cardiac events occurring at two or more sites, and the display provides a histogram of the data as two or more statistical distributions for the two or more sites. In one embodiment, the data includes both sensed intrinsic cardiac events and paced cardiac events. And in another embodiment, the histogram generally comprises a plurality of histogram bins that provide statistical distributions for the cardiac events. Each of the histogram bins generally includes a portion of a first cardiac event distribution and a portion of a second cardiac event distribution.

  • Publication number: 20050033385
    Abstract: Systems and methods for a configurable programmer for an implantable cardiovascular medical device are disclosed. A preferred embodiment comprises a graphical user interface to visualize programming processes to alert a clinician to potential problems with the patient's condition or the therapy provided by the device, or the device itself. The programmer is further adapted to minimize the risk of programming potentially dangerous changes to the implantable device's parameter settings by requiring the clinician to first review new value changes before initiating the programming step. The programmer also allows the clinician to view how a change to one or more parameter settings affect other settings before the implantable device is programmed or re-programmed.

  • Publication number: 20050010258
    Abstract: A medical device programmer graphical user interface, wherein the graphical user interface provides a programmer user with a method of automatically adjusting parameters to be programmed to a medical device in direct response to a user modifying related parameters that are to be programmed to the medical device. The programming interface implements the method in response to the programmer user's use of slide controllers on the programmer display screen to adjust parameters. In response to the on screen parameter changes implemented by the user via slide controller movement, the programmer automatically adjusts related parameters on the display screen by moving slide controllers for related parameters. This automatic adjustment by the programmer graphically illustrates to the user the automatic adjustments being made to the related parameters.

  • Publication number: 20040143305
    Abstract: A cardiac rhythm management system includes techniques for reducing the number of programmable variables associated with maximum pacing rate so that fewer variables are programmed and a reduction in possible parameter conflict is achieved. In an embodiment, a maximum pacing rate parameter replaces a plurality of conventional, separately programmable pacing parameters. For example, maximum tracking rate, maximum sensor rate, rate smoothing maximum pacing rate, atrial pacing preference maximum pacing rate, and ventricular rate regulation maximum pacing rate are replaced by a single maximum pacing rate with, if necessary, a sensor offset and an atrial pacing preference offset. In another example, rate smoothing maximum pacing rate, biventricular trigger maximum pacing rate and ventricular rate regulation maximum pacing rate are replaced by a single maximum pacing rate.

  • Publication number: 20040082976
    Abstract: A system and method for correlating health related data for display. The system includes a medical device recording data and a display producing device which correlates the data and simultaneously displays different types of data or displays two sets of the same type of data along with the circumstances at which the two sets of data were recorded. Such displays aid a physician in prescribing and ascertaining the efficacy of cardiac therapies.

  • Publication number: 20020120311
    Abstract: A medical device programmer and a method of operation in which a first data value is received and used in the execution of one or more algorithms. One or more suggested pulse generator settings are calculated from the one or more algorithms based on the first data value, and the one or more suggested pulse generator settings are displayed on an interactive display screen of the medical device programmer. In one embodiment, the first data value is a duration interval of a QRS complex. From the duration interval, suggestions are made as to one or more ventricular chambers in which to provide pacing pulses. Additionally, pacing intervals for an AV delay are suggested based on measured P-R intervals, or pacing intervals for an LV offset are suggested based on a measured duration interval of a V-V-interval between a right ventricular event and a left ventricular event.
