Abstract
A computer implemented method and system to detect P-waves in cardiac activity is provided. The system includes memory to store specific executable instructions. One or more processors are configured to execute the specific executable instructions for obtaining far field cardiac activity (CA) signals for a series of beats, applying a P-wave template to at least one sub-segment of the CA signals to obtain an alignment indicator and calculating an amplitude dependence (AD) indicator based at least in part on the P-wave template and the at least one sub-segment. The system analyzes the alignment indicator based on a first criteria, compares the AD indicator with a second criteria, designates a candidate P-wave to be an actual P-wave based on the analyzing and comparing and records results of the designating.
