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 system that includes a brain monitoring element, cardiac monitoring element and a processor. The processor is configured to receive a brain signal from the brain monitoring element and a cardiac signal from the cardiac monitoring element. The processor is further configured to determine at least one reference point for a brain event time period by evaluation of the brain signal. The processor further identifies a first portion of the cardiac signal based on the at least one reference point of the brain event time period.
摘要:
A system for regulating or modulating cardiac therapy using brain state information. The modulation may include suppressing standard, prescribed cardiac therapy for a period of time or it may involve modulating the type of cardiac therapy delivered In another embodiment, a system is provided for determining whether a cardiac event is categorized as neurologically matched, and, if so, modulating the therapeutic output to the heart.

摘要:
Methods for receiving a patient mark in an implanted device. A patient may experience symptoms that indicative of a neurological event or are common precursors to more severe clinical symptoms. The patient may activate a patient activator. Activation of the patient activator can cause the patient activator to transmit the patient mark to an implanted device. The implanted device may adjust physiological data being stored in response to the patient mark, including data before and after the patient mark. The patient mark may be used to fine tune the detection algorithms and otherwise tune the detection capability of the implanted device and may also be used as an aid in statistical analysis of the stored physiological data.
摘要:
An assembly for sensing physiologic signals and delivering monopolar stimulation therapy includes a pulse generator, a lead body that is coupled to the pulse generator and includes a first lead, at least one stimulating electrode coupled to the first lead and adapted to receive stimulating pulses from the pulse generator, and a remote electrode that is coupled to the pulse generator and positioned away from the pulse generator.
摘要:
A medical device system and method for monitoring cardiac signal activity in patients with nervous system disorders. In some embodiments, a brain signal and a cardiac signal are received by a processor, brain events are identified in the brain signal, and the brain events are used to identify portions of the cardiac signal. In some embodiments, Event portions of the cardiac signal are identified corresponding to brain event time periods, and Inter-event portions are identified corresponding to time periods between brain events. An Inter-event heart-rate variability (HRV) calculation is performed using Inter-event portions of the cardiac signal, and an output of the medical device system is modified based upon the calculated Inter-event HRV according to certain embodiments of the invention. An Event HRV may also be calculated according to certain embodiments, and an output modified based on comparisons of the Event HRV to the Inter-event HRV, for example.
