摘要： Techniques 'AND SYSTEM (10)' for detection and treatment of myocardial ischemia are described that monitor both the electrical and dynamic mechanical activity of the heart to detect and verify the occurrence of myocardial ischemia in a more reliable manner. The occurrence of myocardial ischemia can be detected by monitoring changes in an electrical signal such as an ECG or EGM, and changes in dynamic mechanical activity of the heart. Dynamic mechanical activity can be represented, for example, by a heart acceleration signal or pressure signal. The electrical signal can be obtained from a set of implanted or external electrodes (16,18,20;22,24,26)' . The heart acceleration signal can be obtained from an single- or multiple-axis accelerometer (88,108)' and/or a pressure sensor deployed within or near the heart. The techniques correlate contractility changes detected by an accelerometer or pressure sensor with changes in the ST electrogram segment detected by the electrodes (16,18,20;22,24,26)' to increase the reliability of ischemia detection.

摘要： In determining whether a patient has ischemia or other conditions discernible in the variation occurring in the ST portion of the electrocardiogram signal, we filter out bad ST change parameters that are not changing at a rate representative of human ischemia ST change parameter rates of change. This can be used for driving therapy systems to alleviate cardiac ischemia. This filtering can be enhanced by using multiple cardiac electrical vectors for the electrogram signal vectors, and using a determination of Axis shift to modify filter parameters and the expected ranges of precursors to the ST change parameter (an ST change variable) to eliminate bad cardiac cycles, that is cardiac cycle information that may be misleading.

摘要： In using electrogram signals to determine physiologic conditions like ischemia, the bad cardiac cycle information due to noise, axis shifts in the cardiac electrical axis, and the like must be removed if the electrogram signal can be made to be a good indicator. If this is accomplished through the adaptive filtering techniques shown here, the signal can be used to drive a closed loop therapy system responsive to those physiologic conditions discernible from good cardiac cycle electrocardiogram signals.

摘要： A system and method for operating an implantable medical device in a disruptive energy field. The system includes an implantable medical device having a control processor and memory. The control processor operates the implantable medical device in a first mode when outside the disruptive energy field, and in a second mode when exposed to a disruptive energy field.

摘要翻译： 在使用电描记图信号来确定生理状况如局部缺血的情况下，如果能够使电描记图信号成为良好的指示器，则必须移除由噪声导致的不良心动周期信息，心电轴的轴位移等。 如果这是通过这里所示的自适应滤波技术来实现的，那么该信号可以用于驱动闭环疗法系统，以响应从良好心动周期心电图信号可辨别的那些生理状况。
