摘要： Techniques are described for selectively enabling and disabling a pre-stimulation passive recharge pacing mode for an implantable medical device (IMD) depending on whether the IMD is operating in an electromagnetic interference (EMI)-safe mode. In some examples, the IMD may enable the pre-stimulation passive recharge pacing mode when the IMD is operating in the EMI-safe mode, and disable the pre-stimulation passive recharge pacing mode when the IMD is not operating in the EMI-safe mode. The EMI-safe mode may be, in some examples, a magnetic resonance imaging (MRI)-safe mode.

摘要： An implantable medical system may include an implantable medical lead including at least one electrode and an implantable medical device. The implantable medical device comprises an electromagnetic interference (EMI) detection module that monitors for one or more particular characteristics of EMI. A control module is configured to control a therapy module to generate single stimulation pulses while operating the IMD in a first operating mode. In response to detecting the condition indicative of the presence of EMI, the control module switches the IMD from the first operating mode to a second operating mode and generates at least one group of two or more stimulation pulses in close proximity to one another in place of a single stimulation pulse while operating the IMD in the second operating mode.

摘要： This disclosure describes techniques for reducing, and possibly eliminating, adverse effects caused by signals induced on an inductive antenna of an implanted medical device by varying magnetic fields from a source of interference, such as the gradient magnetic fields applied during an MRI procedure. For example, the implantable medical device includes an inductive antenna that receives signals via inductive coupling, a filter circuit that attenuates signals induced on the inductive antenna by varying magnetic fields generated from a source of interference and substantially passes signals induced on the inductive antenna by varying magnetic fields generated by an expected source and a telemetry module that processes the signals from the filter circuit.

摘要： An implantable medical device may include a telemetry module, a sensing module, a therapy delivery module, and a processor. The processor may be configured to detect a patient event based on data generated by the sensing module, operate the IMD in a first mode in which the telemetry module is disabled and the therapy delivery module is at least partially disabled when the patient event is not detected, and operate the IMD in a second mode in which the telemetry module is enabled and the therapy delivery module is at least partially disabled when the patient event is detected. In some examples, the processor is configured to, in the second mode, generate a notification of the cardiac arrhythmia and transmit the notification to an external device via the telemetry module. The external device may reside inside an MRI room or outside the MRI room, and may communicate with other devices.

摘要： Techniques are described for controlling effects caused when an implantable medical device (IMD) is subject to a disruptive energy field. The IMD may include an implantable lead that includes one or more electrodes. The IMD may further include a first component having a parasitic inductance. The IMD may further include a second component having a reactance. In some examples, the reactance of the second component may be selected based on the parasitic inductance of the first component such that an amount of energy reflected along the lead in response to energy produced by an electromagnetic energy source is below a selected threshold. In additional examples, the parasitic inductance of the first component and the reactance of the second component are configured such that an amount of energy reflected along the lead in response to a frequency of electromagnetic energy is below a selected threshold.
