Abstract
A computer implemented method and device for providing dual chamber sensing with a single chamber leadless implantable medical device (LIMD) are provided. The method is under control of one or more processors in the LIMD configured with specific executable instructions. The method obtains a far field (FF) cardiac activity (CA) signals for activity in a remote chamber of a heart and compares the far field CA signals to a P-wave template to identify an event of interest associated with the remote chamber. The method sets an atrial-ventricular (AV) delay based on the P-wave identified and delivers pacing pulses at a pacing site of interest to a local chamber based on the AV delay.
