PATIENT CONTROLLED ATRIAL SHOCK THERAPY
First Claim
1. A method of controlling an implantable atrial shock therapy device, comprising:
- detecting an atrial arrhythmia event episode and providing an atrial arrhythmia event status with the implantable device;
detecting a patient activation request originating from external to the implantable device;
generating a message from the implantable device indicating the arrhythmia event status responsive to the detection of the patient activation request; and
requesting and withholding providing of an atrial shock therapy by the implantable device in response to a duration of detection of the detected patient activation request.

Abstract
An implanted cardiac device detects an atrial arrhythmia and provides periodically updated atrial arrhythmia status as long as the arrhythmia is ongoing. A patient may request an indication of ongoing atrial arrhythmia status from external to the patient using a patient activator. The patient activator may include a magnet for closing a reed switch in the implanted device to provide the request or may provide the request over a telemetry link to the implanted device. The implanted device may provide the requested atrial arrhythmia status and other information in the form of an audible tone produced by the implanted device or as a message telemetered from the implanted device to the patient activator. The patient activator may include a tone detector and display for providing a visual indication of the atrial arrhythmia status indication. The magnet activator may also be employed to request or withhold atrial shock therapy.

12. A method for controlling an implantable atrial shock therapy device, comprising:
-
detecting an atrial arrhythmia event episode and automatically updating an atrial arrhythmia event status periodically throughout the duration of a detected atrial arrhythmia event episode with the implantable device; providing a patient activation request to the implantable device from external to the implantable device; and generating a message from the implantable device indicating the periodically updated arrhythmia event status in response to receipt of the patient activation request by the implantable device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
