Patient controlled atrial shock therapy
First Claim
1. A method of controlling an implantable 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, wherein detecting the patient action request includes detecting a magnetic field positioned near the implantable device;
generating a message from the implantable device indicating the arrhythmia event status responsive to the detection of the patient activation request;
requesting an atrial shock therapy by the implantable device in response to the magnetic field being detected for a first duration; and
withholding the atrial shock therapy by the implantable device in response to the magnetic field being detected for a second duration.

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.

11. A method of controlling an implantable 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 an audible tone responsive to the detection of the patient activation request, the audible tone indicating the arrhythmia event status and availability of atrial shock therapy, wherein generating the audible tone includes generating a first audible tone indicating that an atrial arrhythmia event is in progress and that atrial shock therapy is available and a second audible tone distinguishable from the first audible tone, the second audible tone indicating that an atrial arrhythmia event is in progress but that atrial shock therapy is not available; 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.

12. A method for controlling an implantable 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 messages from the implantable device indicating the periodically updated arrhythmia event status in response to receipt of the patient activation request by the implantable device as long as the patient activation request is received by the implantable device. - View Dependent Claims (13, 14, 15, 16, 17, 18)
