Method and apparatus for alleviating cardoversion shock pain
First Claim
1. An atrial defibrillator system, comprising an implantable defibrillator, comprising:
- defibrillation pulse generator means for delivering defibrillation pulses to a patient'"'"'s atria;
means for receiving a request of the patient for atrial defibrillation;
means for delivering a pain alleviating therapy to the patient in response a received request for atrial defibrillation;
delay means for defining a delay period sufficient for the pain alleviating therapy to take effect in response to receipt of the patient'"'"'s request for atrial defibrillation;
means for determining whether the patient'"'"'s heart rhythm indicates a need for atrial fibrillation on expiration of the delay period; and
means responsive to a determination that the patient'"'"'s heart rhythm indicates a need for atrial fibrillation on expiration of the delay period for triggering the defibrillation pulse generator to deliver an atrial defibrillation pulse.

Abstract
An implantable cardioverter for providing cardioversion electrical energy to at least one chamber of a patient'"'"'s heart in need of cardioversion and applying a pain alleviating therapy at an appropriate site in the patient'"'"'s body prior to or in conjunction with the delivery of the cardioversion energy to the heart chamber to alleviate propagated pain perceived by the patient. The combined cardioversion and pain alleviating therapies are preferably realized in a single implantable, multiprogrammable medical device or separate implantable cardioversion and pain control devices with means for communicating operating and status commands between the devices through the patient'"'"'s body.

8. A method of atrial defibrillation, comprising:
-
implanting an atrial defibrillator comprising a defibrillation pulse generator, means for receiving a request of the patient for atrial defibrillation, means for delivering a pain alleviating therapy to the patient, means for determining whether the patient'"'"'s heart rhythm indicates a need for atrial fibrillation and delay means for defining a delay period; the patient requesting atrial defibrillation; in response a received request for atrial defibrillation, employing the delay means to define a delay period sufficient for the pain alleviating therapy to take effect; in response to a received request for atrial defibrillation employing the means for delivering a pain alleviating therapy to the patient to deliver the pain alleviating therapy to the patient; in response to expiration of the delay interval, employing the means for determining whether the patient'"'"'s heart rhythm indicates a need for atrial fibrillation to determine whether atrial defibrillation is needed; and
,in response to an indicated need for atrial defibrillation, employing the defibrillation pulse generator to deliver an atrial defibrillation pulse to the patient'"'"'s atria. - View Dependent Claims (9, 10, 11, 12, 13, 14)
