摘要： Implantable electromedical device or loop recorders or ILRs that solve the problem of very low arrhythmia detection specificities in, i.e., high number of false positives, based on detection and analysis of external noise, specifically muscle noise surrounding the electromedical device. Embodiments generally employ active detection of lead or device movement that induces signal artifacts indicative of external noise. One or more embodiments may detect lead or device movement through use of a piezoelectric transducer, for example located proximally to the device or in the lead of the electromedical.

摘要： Detects external noise using a motion sensor signal for example to increase the specificity of arrhythmia detections based on active muscle noise detection. Whenever a motion signal is present that is below or above a certain frequency, for example 5 Hz, or within a certain frequency range, for example 1 to 10 Hz, and/or above a certain amplitude, for example greater than 1 mg, or close to a known motion pattern, then the detection of fast ventricular arrhythmia is suspended. For the detection of slow arrhythmia, for example asystole or syncope, an episode is confirmed when a short lasting motion sensor signal occurs. Uses a motion sensor based signal, for example as obtained from an accelerometer on an implantable electrode lead and/or implantable device.

摘要： One embodiment of the present invention relates to an implantable medical device (“IMD”) that can be programmed from one operational mode to another operational mode when in the presence of electro-magnetic interference (“EMI”). In accordance with this particular embodiment, the IMD includes a communication interface for receiving communication signals from an external device, such as a command to switch the IMD from a first operation mode to a second operation mode. The IMD further includes a processor in electrical communication with the communication interface, which is operable to switch or reprogram the IMD from the first operation mode to the second operation mode upon receiving a command to do so. In addition, the IMD includes a timer operable to measure a time period from when the processor switches the IMD to the second operation mode. In accordance with this aspect of the invention, the processor is in electrical communication with the timer, and is further operable to switch the IMD from the second operation mode back to the first operation mode when the measured time period reaches a predetermined time period.
