摘要： An implantable medical device (IMD) includes a lead having one or more sensing electrodes and one or more therapy delivery electrodes, and a sensor configured to detect the presence of static and time-varying scan fields in a magnetic resonance imaging (MRI) environment. A controller, in electrical communication with the lead and the sensor, is configured to process signals related to tachycardia events sensed via the one or more sensing electrodes and to deliver pacing and shock therapy signals via the one or more therapy delivery electrodes. The controller compares the sensed static and time-varying scan fields to static and time-varying scan field thresholds. The controller controls delivery of anti-tachycardia pacing and shock therapy signals as a function of the detected tachycardia events, the comparison of the sensed static scan field to the static scan field threshold, and the comparison of the time-varying scan fields to the time-varying scan field thresholds.

摘要： A medical device lead includes a proximal connector configured to couple the lead to a pulse generator, and an insulative lead body extending distally from the proximal connector. A first lead conductor is coupled to the proximal connector and extends through the lead body. The medical device lead also includes a distal defibrillation electrode. A first spark gap is connected between the first lead conductor and the distal defibrillation electrode and has a breakdown voltage that prevents transmission of magnetic resonance imaging (MRI) induced signals from the first lead conductor to the distal defibrillation electrode in an MRI environment and allows transmission of therapy signals to the distal defibrillation electrode.

摘要： Energy delivered from an implantable medical device to stimulate tissue within a patient's body is controlled. An electrical signal used to stimulate the tissue is changed from a first energy state to a second energy state during a magnetic resonance imaging (MRI) scan. The energy delivered is maintained at the second energy state after the MRI scan. A capture threshold of the tissue is then measured, and the energy delivered to the tissue is adjusted based on the measured capture threshold of the tissue.

摘要： Systems and methods for arrhythmia therapy in MRI environments are disclosed. Various systems disclosed utilize ATP therapy rather than ventricular shocks when patients are subjected to electromagnetic fields in an MRI scanner bore and shock therapy is not available. As the patient is moved out from within the scanner bore and away from the MRI scanner, the magnetic fields diminish in strength eventually allowing a high voltage capacitor within the IMD to charge if necessary. The system may detect when the electromagnetic fields no longer interfere with the shock therapy and will transition the IMD back to a normal operational mode where shock therapy can be delivered. Then, if the arrhythmia still exists, the system will carry out all of the system's prescribed operations, including the delivery of electric shocks to treat the arrhythmia.
摘要翻译：公开了MRI环境中心律失常治疗的系统和方法。所公开的各种系统利用ATP治疗而不是心室休克，当患者在MRI扫描器孔中经受电磁场并且不能使用休克疗法时。当患者从扫描仪孔内移出并远离MRI扫描仪时，磁场的强度减弱，最终允许IMD内的高电压电容器根据需要进行充电。该系统可以检测何时电磁场不再干扰休克疗法，并将IMD转移回正常的操作模式，其中可以提供休克疗法。那么，如果心律失常仍然存在，系统将执行系统的所有规定的操作，包括交付电击治疗心律失常。

摘要： Systems and methods for checking the connection of a lead to an implantable medical device implanted within a patient's body are disclosed. An illustrative method includes measuring at least one characteristic associated with the lead connection to the implantable medical device prior to an MRI scan. The method further includes comparing the at least one measured characteristic with a threshold parameter programmed within the implantable medical device. The method further includes setting a flag in the implantable medical device upon the at least one measured characteristic satisfying at least one condition associated with the threshold parameter for a predetermined period of time. The flag indicates a disconnection of the lead from the implantable medical device.
