1. A method for delivery of anti-tachycardia pacing (ATP) therapy by a cardiac rhythm management device, comprising:
- monitoring cardiac electrical activity in order to detect an arrhythmia;
upon detection of a terminable arrhythmia, delivering ATP therapy in accordance with a first pacing protocol selected from a library containing pacing parameter sets corresponding to a plurality of such protocols, wherein the protocol is selected in accordance with information recorded in a result table; and
, tabulating the success or failure of the ATP therapy using the selected protocol in the result table.

Abstract
A method and apparatus for delivering anti-tachycardia pacing in an adaptive manner is disclosed. A cardiac rhythm management device, such as an implantable pacemaker, having anti-tachycardia pacing capability delivers anti-tachycardia pacing therapy in accordance with a selected pacing protocol upon detection of a terminable arrhythmia. The protocol is selected from a library of available protocols. A record of the successes and failures of each available protocol in converting tachyarrhythmias is maintained in a result table for use in selecting the protocol.
