摘要：
In situations in which an implantable medical device (IMD) (e.g., an extravascular ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the IMD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the IMD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the IMD includes a pace pulse detector that detects, based on the processing of sensed electrical signals, delivery of a pacing pulse from a second implantable medical device and blank, based on the detection of the pacing pulse, the sensed electrical signal to remove the pacing pulse from the sensed electrical signal.
