Apparatus and method for antitachycardia pacing in a arrhythmia control systems
First Claim
1. A method of treating tachycardias comprising the steps of:
- A) selecting a range of tachycardia cycle lengths for which antitachycardia pacing treatment is desired;
B) selecting a plurality of sub-ranges of tachycardia cycle lengths from said range of tachycardia cycle lengths;
C) providing a plurality of storage locations corresponding to said tachycardia cycle length sub-ranges;
D) storing, in corresponding ones of said storage locations, corresponding antitachycardia pacing parameters which have been successful in reverting previous tachycardias having cycle lengths that fall in said corresponding tachycardia cycle length sub-ranges; and
,E) treating subsequent tachycardias using antitachycardia pacing parameters selected from storage locations that correspond to, or are closest to correspondence with, tachycardia sub-ranges corresponding to the tachycardias to be treated.

Abstract
A method and apparatus for treating tachycardias are disclosed which utilize tachycardia cycle lengths in connection with selecting the type of antitachycardia pacing to be used in such treatment. A range of tachycardia cycle lengths is selected for which antitachycardia pacing treatment is indicated. This range is divided into a plurality of sub-ranges of tachycardia cycle lengths, and corresponding storage locations are established for each of the tachycardia cycle length sub-ranges. Antitachycardia pacing parameters which have been successful in reverting previous tachycardias are stored in their corresponding storage locations, and subsequent tachycardias are treated using antitachycardia pacing parameters selected from storage locations that correspond to, or are closest to correspondence with, the storage locations corresponding to the tachycardias to be treated.

13. Apparatus for treating tachycardias having cycle lengths within a predetermined range of tachycardia cycle lengths, comprising:
-
A) means for establishing a plurality of storage locations each of which corresponds to a generally different sub-range of tachycardia cycle lengths within said range of tachycardia cycle lengths; B) means for storing, in corresponding ones of said storage locations, corresponding antitachycardia pacing parameters which have been successful in reverting previous tachycardias having cycle lengths that fall in said corresponding tachycardia cycle length sub-ranges; and C) means for treating subsequent tachycardias using antitachycardia pacing parameters selected from storage locations that correspond to, or are closest to correspondence with, the tachycardia sub-ranges corresponding to the tachycardias to be treated. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
