    摘要： Embodiments described herein relate to implantable medical devices (IMDs) and methods for use therewith. Such a method includes, during each of a plurality of message alert periods during which a communication capability of the IMD is enabled, determining whether a valid message is detected. In response to determining that no valid message was detected during a message alert period, the communication capability of the IMD is temporarily disable for a disable period. A length of the disable period may be increased in response to no valid message being detected during two consecutive message alert periods. A length of the disable period may be dependent on an operational mode of the IMD, such that the length of the disable period differs for different operational modes. The IMD may also enter a noise state, and remain in the noise state until the IMD receives a specified number of valid messages.

    摘要： Apparatus and methods for the management and safety monitoring of temporary cardiac pacing devices adapted to monitor a cardiac pacing device, the apparatus comprising; electrical connections with the heart and with the pacing device; a signal acquisition module adapted to acquire via the electrical connections cardiac signals indicative of cardiac operation, pacing impulses emitted by the pacing device, evoked signals emitted from the heart in response to the pacing impulses, and any unidentified noise signals; a processor adapted to receive from the signal acquisition module and to analyse the cardiac and evoked signals, the pacing impulses and any noise signals; a data store, and a display, wherein the processor is adapted to: i. establish a base level operation of the heart and pacing device and to store the associated quality, size and/or timing values of the cardiac and evoked signals and the pacing impulses in the date store; ii, receive instantaneous values of quality, size and/or timing values of the cardiac and evoked signals and the pacing impulses and to cause the display to show these values; iii. compare the instantaneous values against the values in the data store to establish differences therebetween; iv. analyse; a, any noise signal received, b. the instantaneous values received at step ii above, and c. any difference(s) at step iii above in terms of its/their quality, size and timing, and v, raise an alarm in the event a noise signal occurs and/or no evoked signal is received,
