1. A system to optimize cardiac monitoring resources, comprising: a signal receiver circuit configured to receive cardiac electrical information of a subject; and an assessment circuit configured to:
detect a premature ventricular contraction (PVC) event in a first detection window using the received cardiac electrical information from the first detection window, wherein the first detection window comprises a number of cardiac intervals or a time period comprising a plurality of cardiac intervals;
determine a count of detected PVC events in the first detection window;
remove cardiac electrical information associated with the detected PVC event from the first detection window if the count of detected PVC events in the first detection window is below an upper threshold; and
detect an indication of atrial fibrillation of the subject for the first detection window using remaining cardiac electrical information in the first detection window.
