Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 10:
11. A system, comprising:
electrodes;
an implantable medical device (IMD) coupled to the electrode, the IMD configured to sense near field (NF) and far field (FF) signals between the electrodes for multiple beats;
memory to store the NF and FF signals and to store program instructions; and
a processor that, when executing the program instructions, is configured to:
apply an arrhythmia detection algorithm to the NF signals for identifying events within the NF signal;
monitor the events to detect a candidate arrhythmia condition in the NF signals based on the events identified for the corresponding multiple beats;
identify the candidate arrhythmia condition to be an under-detected arrhythmia based on the events identified;
in response to the identification of the under-detected arrhythmia, analyze the FF signals for a presence of an under-detected arrhythmia indicator; and
deliver an arrhythmia therapy based on the presence of the under-detected arrhythmia indicator in the FF signals and the identification of the under-detected arrhythmia in the NF signals.
