Systems and methods of alarm validation and backup in implanted medical devices
First Claim
1. A monitoring system for a human patient including:
- an implanted medical device including;
a first internal patient alerting sub-system capable of generating at least a first internal alarm signal;
at least one sensor configured to sense actuation of the first internal patient alerting sub-system;
at least one sensor for sensing data for calculating a medical condition of the human patient;
a wireless communications system;
a processor, the processor configured to detect abnormalities in the patient'"'"'s medical condition, the processor further configured to actuate the first internal patient alerting sub-system following detection of abnormalities in the patient'"'"'s medical condition, the processor also configured to perform an alarm test;
the alarm test including both actuation of the first internal patient alerting sub-system for at least one test interval and measurement by the processor of the first internal alarm signal generated by the first internal patient alerting sub-system during the test interval, the processor further configured to detect at least one of sufficiency and insufficiency in the first internal alarm signal during the test interval;
external equipment including wireless communication designed to receive signals from the implanted medical device; and
,a secondary patient alerting sub-system capable of generating a second alarm signal, designed to notify the patient when insufficiency is detected in the first internal alarm signal.

Abstract
Alarm tests are disclosed which use alarm test signals to assess alarms provided by medical devices. Especially relevant are implanted devices that monitor cardiac activity and provide notification in response to medically relevant events. Alarm tests can occur periodically, or in response to a patient, doctor, or remote party initiating the alarm test. Alarm tests can also occur during the actual alarms issued to detected medical events. Alarm tests lead to pass or fail results, which in turn may cause operations to contingently occur. Alarm test failure in the auditory, visual, or tactile modality, may cause an alternatively defined alarm signal to be used as back-up. Alarm test logs can store alarm test results, including quantification of the measured alarm signal. Rapid alarm tests are described, as are various methods of accurately measuring characteristics of the test signal in ambulatory patients, which are especially relevant to a vibration alarm.
