    • The present invention provides a subcutaneous (or submuscular) single or multiple-electrode array that provides various embodiments of a compliant surround shroud coupled to a peripheral portion of an implantable medical device (IMD). The shroud incorporates a plurality of substantially planar electrodes mechanically coupled within recessed portions of the shroud. These electrodes electrically couple to IMD circuitry to monitor cardiac activity of a subject. Temporal recordings of the detected cardiac activity are referred to herein as an extra-cardiac electrogram (EC-EGM). The recordings can be stored upon computer readable media within an IMD at various resolution (e.g., continuous beat-by-beat, periodic, triggered, mean value, average value, etc.). Real time or stored EC-EGM signals can be provided to remote equipment via telemetry. For example, when telemetry, or programming, head of an IMD programming apparatus is positioned within range of an IMD the programmer receives some or all of the EC-EGM signals.
    • 本发明提供皮下(或肌内)单电极阵列或多电极阵列,其提供耦合到可植入医疗装置(IMD)的周边部分的顺应性环绕护罩的各种实施例。 护罩包括多个基本上平面的电极,机械耦合在护罩的凹陷部分内。 这些电极电耦合到IMD电路以监测受试者的心脏活动。 检测到的心脏活动的时间记录在本文中称为心外电图(EC-EGM)。 记录可以以各种分辨率(例如,连拍,逐周期,触发,平均值,平均值等)存储在IMD内的计算机可读介质上。 可以通过遥测提供实时或存储的EC-EGM信号到远程设备。 例如,当遥测或编程时,IMD编程设备的头部位于IMD的范围内,程序员接收部分或全部EC-EGM信号。
