Abstract

A system and method of enabling detection enhancements selected from a plurality of detection enhancements. In a system having a plurality of clinical rhythms, including a first clinical rhythm, where each of the detection enhancements is associated with the clinical rhythms, the first clinical rhythm is selected. The first clinical rhythm is associated with first and second detection enhancements. When the first clinical rhythm is selected, parameters of the first and second detection enhancements are set automatically. A determination is made as to whether changes are to be made to the parameters. If so, one or more of the parameters are modified under user control.

Claims

1. A programmer for use by a user to program an implantable cardioverter defibrillator, the programmer comprising:

a programming screen;

a selection module adapted to receive from the user a first selection of one or more detection enhancements from a plurality of detection enhancements being rules for determining whether to deliver a shock therapy from the implantable cardioverter defibrillator in response to a detection of tachyarrhythmia;

a rate smoothing button on the programming screen, the rate smoothing button adapted to receive from the user a second selection between enabling and disabling a rate smoothing feature of the implantable cardioverter defibrillator; and

a communication module adapted to program the implantable cardioverter defibrillator according to the first selection and the second selection.

2. The programmer of claim 1, wherein the rate smoothing button is displayed on the programming screen in a manner allowing the user to enable the rate smoothing feature when the rate smoothing feature is disabled and to disable the rate smoothing feature when rate smoothing feature is enabled.

3. The programmer of claim 1, comprising a parameter modification module coupled to the selection module, the parameter modification module adapted to receive parameters related to the selected one or more detection enhancements, and wherein the communication module is adapted to program the parameters into the implantable cardioverter defibrillator.

4. The programmer of claim 3, comprising:

a zone rate bar displayed on the programming screen, the zone rate bar presenting a plurality of tachyarrhythmia zones each associated with one or more detection enhancements of the plurality of detection enhancements;

detection buttons displayed on the programming screen, the detection buttons each associated with an arrhythmia zone of the plurality of tachyarrhythmia zones and adapted to allow display of a detection parameter summary for that tachyarrhythmia zone and access to the detection parameters associated with that tachyarrhythmia zone; and

therapy buttons displayed on the programming screen, the therapy buttons each associated with a tachyarrhythmia zone of the plurality of tachyarrhythmia zones and adapted to allow display of a therapy parameter summary for that tachyarrhythmia zone and access to the therapy parameters for that tachyarrhythmia zone.

5. The programmer of claim 4, comprising a bradycardia therapy summary displayed on the programming screen, the bradycardia therapy summary presenting bradycardia therapy parameters and allowing access to the presented bradycardia therapy parameters.

6. The programmer of claim 5, wherein the zone rate bar comprises labels each representing one tachyarrhythmia zone of the plurality of tachyarrhythmia zones.

7. The programmer of claim 6, wherein the zone rate bar comprises changeable rate threshold values each associated with one tachyarrhythmia zone of the plurality of tachyarrhythmia zones.

8. The programmer of claim 6, wherein the zone rate bar comprises labels representing one or more of atrial tachyarrhythmia, sinus tachycardia, polymorphic ventricular tachyarrhythmia, and ventricular fibrillation.

9. A method for operating a programmer for an implantable cardioverter defibrillator, the method comprising:

receiving from a user a first selection of one or more detection enhancements from a plurality of detection enhancements being rules for determining whether to deliver a shock therapy from the implantable cardioverter defibrillator in response to a detection of tachyarrhythmia;

displaying a rate smoothing button on a programming screen of the programmer, the rate smoothing button adapted to receive from the user a second selection between enabling and disabling a rate smoothing feature of the implantable cardioverter defibrillator; and

programming the implantable cardioverter defibrillator according to the first selection and the second selection.

10. The method of claim 9, wherein displaying the rate smoothing button comprises displaying the rate smoothing button in a manner allowing the user to enable the rate smoothing feature when the rate smoothing feature is disabled and to disable the rate smoothing feature when rate smoothing feature is enabled.

11. The method of claim 9, comprising:

setting detection enhancement parameters associated with the first selection; and

programming the detection enhancement parameters into the implantable cardioverter defibrillator.

12. The method of claim 11, wherein setting the detection enhancement parameters comprises:

setting the detection enhancement parameters to stored detection enhancement parameter values; and

receiving from the user one or more modifications to the detection enhancement parameters.

13. The method of claim 11, wherein programming the detection enhancement parameters into the implantable cardioverter defibrillator comprises programming the implantable cardioverter defibrillator to perform one or more of delaying the shock therapy, inhibiting shock therapy, bypassing an inhibition of the shock therapy, and bypassing another therapy in favor of the shock therapy.

14. The method of claim 13, wherein receiving from the user the first selection comprises receiving from the user a selection of one or more of:

delivering the shock therapy if a ventricular rate is greater than an atrial rate;

inhibiting the shock therapy if the atrial rate is greater than a threshold atrial rate;

inhibiting the shock therapy if the ventricular rate is unstable;

inhibiting the shock therapy if a heart rate increases gradually;

delivering the shock therapy if a ventricular rhythm is determined to be unstable; and

delivering the shock therapy if a high heart rate continues throughout a programmed time period.

15. The method of claim 11, comprising:

displaying on the programming screen a plurality of tachyarrhythmia zones each associated with one or more detection enhancements of the plurality of detection enhancements;

displaying on the programming screen a plurality of detection buttons each associated with an arrhythmia zone of the plurality of tachyarrhythmia zones; and

in response to selection of a detection button of the plurality of detection buttons, the selected detection button associated with a selected tachyarrhythmia zone of the plurality of tachyarrhythmia zones, displaying a detection parameter summary for the selected tachyarrhythmia zone to allow access to the detection parameters associated with the selected tachyarrhythmia zone.

16. The method of claim 15, comprising:

displaying on the programming screen a plurality of therapy buttons each associated with an arrhythmia zone of the plurality of tachyarrhythmia zones; and

in response to selection of a therapy button of the plurality of therapy buttons, the selected therapy button associated with a selected tachyarrhythmia zone of the plurality of tachyarrhythmia zones, displaying a therapy parameter summary for the selected tachyarrhythmia zone to allow access to the therapy parameters associated with the selected tachyarrhythmia zone.

17. The method of claim 16, comprising displaying on the programmer screen a bradycardia therapy summary presenting, and allowing access to, bradycardia therapy parameters.

18. A programmer for use by a user to program an implantable cardioverter defibrillator, comprising:

means for receiving from a user a first selection of one or more detection enhancements from a plurality of detection enhancements being rules for determining whether to deliver a shock therapy from the implantable cardioverter defibrillator in response to a detection of tachyarrhythmia;

means for receiving from the user a second selection between enabling and disabling a rate smoothing feature of the implantable cardioverter defibrillator; and
