Method and apparatus for generation and selection of tachycardia therapy hierarchy
First Claim
Patent Images
1. A method for providing therapy in an implantable medical device, comprising:
- detecting a tachycardia event;
determining a characteristic of the detected tachycardia event;
selecting a hierarchy of therapies to treat the detected tachycardia event in response to the determined characteristic;
applying a therapy corresponding to the selected hierarchy of therapies;
determining whether the applied therapy terminates the detected tachycardia event;
storing historical effectiveness of the applied therapy; and
updating the selected hierarchy of therapies in response to the stored historical effectiveness.

Abstract
A method and apparatus for generating and selecting therapies, or hierarchies of therapies, that may be used to treat episodes of atrial or ventricular tachycardia. A characteristic of a detected tachycardia event is determined, and a hierarchy of therapies to treat the detected tachycardia event is selected in response to the determined characteristic.

6. A method for providing therapy in an implantable medical device, comprising:
-
detecting a tachycardia event; determining a characteristic of the detected tachycardia event; and selecting a hierarchy of therapies to treat the detected tachycardia event in response to the determined characteristic, wherein determining the characteristic of the tachycardia event comprises; comparing the characteristic to a corresponding characteristic template; computing a degree of resemblance between the characteristic and the corresponding characteristic template; and determining that the characteristic matches the corresponding characteristic template in response to the degree of resemblance exceeding a predetermined threshold, and wherein selecting a hierarchy of therapies comprises selecting a hierarchy associated with the corresponding characteristic template in response to determining that the characteristic matches the corresponding characteristic template. - View Dependent Claims (7)

8. An implantable medical device, comprising:
-
a plurality of electrodes detecting a tachycardia event; a processor determining a characteristic of the detected tachycardia event and selecting a hierarchy of therapies to treat the detected tachycardia event in response to the determined characteristic; and a storage device, wherein the processor applies a therapy, via the plurality of electrodes, corresponding to the selected hierarchy of therapies, determines whether the applied therapy terminates the detected tachycardia event, stores historical effectiveness of the applied therapy in the storage device, and updates the selected hierarchy of therapies in response to the stored historical effectiveness. - View Dependent Claims (9, 10, 11, 12)
