摘要：
A distributed leadless implantable system and method are provided that comprise a leadless implantable medical device (LIMD). The LIMD comprises a housing having a proximal end configured to engage local tissue of interest in a local chamber, cardiac sensing circuitry to sense cardiac signals and a controller configured to analyze the cardiac signals and, based thereon, to produce a near field (NF) event marker indicative of a local event of interest (EOI) occurring in the local chamber. The system and method further comprise a subcutaneous implantable medical device (SIMD). The SIMD comprises cardiac sensing circuitry to sense cardiac signals, a controller configured to identify a candidate EOI from the cardiac signals, and pulse sensing circuitry to detect the NF event marker from the LIMD. The SIMD controller is configured to declare the candidate EOI as a valid EOI or an invalid EOI based on the NF event marker.
