1. A system, comprising:
a signal receiver circuit configured to receive cardiac electrical information of a subject; and
an assessment circuit for performing event detection, the assessment circuit configured to:
determine a set of arrhythmia parameters for a detection window interval using the received cardiac electrical information of the subject, the set including at least one arrhythmia parameter; and
detect, for the detection window interval, an initial arrhythmia event indication using the determined set of arrhythmia parameters and a respective set of parameter thresholds,
wherein, after a threshold amount of detection window intervals detecting the initial arrhythmia event indication, the assessment circuit is configured to dynamically adjust the event detection for subsequent detection window intervals until an exit criteria is detected, comprising to:
dynamically adjust, between a current sensitivity setting and a most sensitive sensitivity setting, including at least three adjustments between an initial detection setting and the most sensitive sensitivity setting, at least one of the respective set of parameter thresholds to increase sensitivity of an extended arrhythmia event indication detection using the at least one of the respective set of parameter thresholds.
