1. A system configured to be communicatively coupled to an implantable medical device sensing one or more cardiac signals indicative of one or more arrhythmia episodes and produce cardiac data representative of the one or more cardiac signals, the system comprising: an arrhythmia analysis circuit configured to receive cardiac data transmitted from the implantable medical device, perform automatic adjudication of each episode of one or more arrhythmia episodes using the cardiac data by executing a plurality of adjudication algorithms to produce voting classifications for each episode, determining a voting classification of the voting classifications for each episode by executing an adjudication algorithm of the plurality of adjudications algorithms, determining an episode classification for each episode using one or more primary voting classifications selected from the voting classifications and a confidence level in the episode classification based on the voting classifications for each episode, and generate episode data representative of information associated with each episode including the episode classification and the confidence level in the episode classification; a memory circuit configured to store data including the cardiac data and the episode data; and a user interface including a presentation device configured to present the information associated with each episode.
