Abstract: Systems and methods for detecting arrhythmias in cardiac activity are provided and include memory to store specific executable instructions. One or more processors are configured to execute the specific executable instructions for obtaining first and second far field cardiac activity (CA) data sets over primary and secondary sensing channels, respectively, in connection with a series of beats. The system detects candidate atrial features from the second CA data set, identifies ventricular features from the first CA data set and utilizes the ventricular features to separate beat segments within the second CA data set. The system automatically iteratively analyzes the beat segments by overlaying an atrial activity search window with the second CA data set and determines whether one or more of the candidate atrial features occur within the atrial activity search window.

Abstract: A system and method for accelerating confirmation of cardiac arrhythmias 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 a far field cardiac activity (CA) data set that includes far field CA signals for a series of beats. The CA data set includes a first CA data subset and a remainder CA data subset. The system analyzes the CA data set for an arrhythmia of interest utilizing a primary detection process having primary criteria. During a first phase of the primary detection process the system analyzes the first CA data subset to determine whether the first CA data subset satisfies at least a portion of the primary criteria. When the first CA data subset satisfies at least the portion of the primary criteria, the system initiates a secondary confirmation process.
