Patent ID: 8827904

Claim:
A method for monitoring a physiological parameter of a patient detected by an implantable medical device system comprising an implantable medical device, an external device and a processor configured to perform the method, comprising the steps of: monitoring the physiological parameter with the implantable medical device to determine if the physiological parameter exceeds an alert threshold and if the physiological parameter returns to a non-alert level; if the physiological parameter exceeds an alert threshold: scheduling a series of interrogation sessions between the implantable medical device and the external device to occur at predetermined time intervals; transmitting data corresponding to the physiological parameter from the implantable medical device to the external device; and continuing monitoring the physiological parameter with the implantable medical device; then if the physiological parameter has returned to a non-alert level: automatically canceling at least one pending scheduled interrogation session of the series of interrogation sessions; and automatically returning to the monitoring the physiological parameter with the implantable medical device; and initiating transmitting data step by the external device “waking up” the implantable medical device.
