摘要： Various implantable medical devices (IMDs) are disclosed for implantation in a patient. The IMD includes pacing circuitry configured to selectively produce pacing pulses at a programmable pacing rate. In one embodiment, the IMD is configurable to subject a patient to a stress test. The IMD may be configurable to subject the patient to the stress test at the time specified by stored timing information, or in response to a signal (e.g., from a patient activator). Another embodiment of the implantable medical device (IMD) includes sensor circuitry, a memory for storing data, and a control unit. The sensor circuitry produces sensor data relating to cardiac condition. The control unit is configurable to store the sensor data in the memory until a trigger signal is received. Methods are described for performing a stress test in a patient with an IMD, and for subsequently reproducing cardiac operational states.

摘要： Techniques 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 that are sensed by an accelerometer sensor. The heart acceleration signal can be obtained from an single- or multiple-axis accelerometer 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 to increase the reliability of ischemia detection.

摘要： Techniques 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. The heart acceleration signal can be obtained from an accelerometer or 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 to increase the reliability of ischemia detection.

摘要： An implantable medical device (IMD) performs periodic testing of a patient to determine ischemia threshold information. At selected times while the patient is at rest, the IMD increases the pacing rate over time until it receives feedback either from the patient or from an ischemia sensor. The IMD determines the threshold based upon the pacing rate at the time when the feedback was received. The threshold information can be used to adjust the upper pacing rate that can be used during rate adaptive pacing, to determine the effects of drug therapy, and to provide a general indication of the state of coronary artery disease in the patient. The periodic increase of pacing rate to the ischemic zone also provides a preconditioning of the myocardium to allow the patient greater exercise benefit without angina.

摘要： An implantable barometric pressure sensor coupled with an implantable medical device (IMD) provides a barometric pressure related, reference pressure value for use in combination with an absolute pressure value measured by an implantable absolute pressure sensor coupled to the IMD. In one embodiment, the barometric pressure sensor is implanted under the skin and subcutaneous tissue layer at or near the implant site of the IMD. In variations of this embodiment, the barometric pressure is formed as part of a connector module of the IMD or extends from the connector module. In a further embodiment, a percutaneous access device is provided which is adapted to be implanted to extend through the skin and subcutaneous tissue layer of the patient and is coupled with the barometric pressure sensor to provide for an air chamber extending between the atmosphere and the barometric pressure sensor. The barometric pressure sensor is preferably enclosed within an air chamber of the implantable medical device, and a catheter extends between the air chamber of the implantable medical device and the percutaneous access device. Or the barometric pressure sensor is enclosed within an air chamber of the percutaneous access device, and a lead extends between the barometric pressure sensor and the implantable medical device.
