    摘要： Methods of generating an extended cluster are disclosed. A first cluster including data representative of a first signal indicative of an abnormal physiological symptom is generated. A second signal is detected as representing a second abnormal physiological symptom and the second abnormal physiological symptom continues after the first abnormal physiological symptom ends. An extended cluster including the data from the first signal and the second signal is generated that extends from the time when the first abnormal physiological symptom occurs to the time when the second abnormal physiological symptom ends. The first and the extended cluster may include data of both the first and second signals the entire period of the clusters. If desired, the first signal or the second signal may be provided from a sensor implanted in a patient's brain tissue.

    摘要： A medical device senses electrical activity within a patient and, in some embodiments, delivers stimulation to the patient via a plurality electrical paths, which include electrodes and associated conductors of one or more leads. The medical device determines whether a symptomatic event, such as a seizure, is detected based on the sensed electrical activity, and measures the impedance of one or more of the paths in response to the determination. If the medical device identifies a dysfunctional electrical path based on the measured impedance, the device may, as examples, disable the dysfunctional electrical path, or modify a stimulation or sensing program to not use the dysfunctional electrical path. In this manner, the medical device may identify inaccurate symptomatic event detection and, where the device delivers a therapy in response to such detection, such as stimulation via the electrical paths, avoid inappropriate therapy delivery.

    摘要： Apparatus for storing data records associated with a medical monitoring event in a data structure. Upon indication by a patient of a possible manifestation of a neurological event, the implanted device obtains and stores data in the data record in a first data structure that is age-based. Before an oldest data record is lost, the oldest data record may be stored in a second data structure that is priority index-based. The priority index may be determined by a severity level and may be further determined by associated factors. The implanted device may organize, off-load, report, and/or display a plurality of data records based on an associated priority index. Additionally, the implanted device may select a subset or composite of physiologic channels from the available physiologic channels based on a selection criterion.

    摘要： Methods and apparatus for storing data records associated with a medical monitoring event in a data structure. Upon detection of a possible occurrence of a physiological event by one group of monitoring elements, an implanted device records data received from another group of monitoring elements. The implanted device obtains and stores the data in the data record in a first data structure that is age-based. Before an oldest data record is lost, the oldest data record may be stored in a second data structure that is priority index-based. The priority index may be determined by a severity level and may be further determined by associated factors. The implanted device may organize, off-load, report, and/or display a plurality of data records based on an associated priority index. Additionally, the implanted device may select a subset or composite of physiologic channels from the available physiologic channels based on a selection criterion.

    摘要： Methods and apparatus for storing data records associated with an extreme value are disclosed. Signal data is stored in a first buffer of a set of buffers. If a local extreme value for the first buffer exceeds a global extreme value, signal data is stored in a second buffer of the set of buffers. This process is repeated, wrapping around and overwriting buffers until the signal data in a current buffer does not have a local extreme value that exceeds the global extreme value. When this happens, signal data may be stored in a subsequent buffer and if a local extreme value of the subsequent buffer does not exceed the global extreme value, further signal data may be stored in the subsequent buffer in a circular manner until either an instantaneous extreme value exceeds the global extreme value or the recording period ends. In an embodiment, the extreme value may be a peak value.
