1. A system, comprising:
a HIS electrode configured to be located proximate to a HIS bundle and to at least partially define a HIS sensing vector;
memory to store program instructions and cardiac activity (CA) signals for a series of beats utilizing a candidate sensing configuration, the candidate sensing configuration defined by i) the HIS sensing vector and ii) a sensing channel that utilizes sensing circuitry configured to operate based on one or more sensing settings to detect near field and far field activity;
one or more processors that, when executing the program instructions, are configured to:
analyze the CA signals to obtain an atrial (A) feature of interest (FOI) and a ventricular (V) FOI for corresponding beats within the series of beats;
identify a V-A FOI relation between the A FOIs and the V FOIs across the series of beats;
adjust the candidate sensing configuration between at least one of multiple HIS sensing vectors or multiple sensing settings, and repeat the obtain, analyze and identify operations to obtain a collection of V-A FOI relations for a corresponding collection of candidate sensing configurations; and
select a resultant sensing configuration from the collection of candidate sensing configurations based on one or more criteria, the resultant sensing configuration to be utilized to manage HIS bundle pacing during an atrial arrhythmia.
