1. A method of detecting arrhythmic electrocardiogram (ECG) signals, the method comprising:
- monitoring one or more physiological parameters associated with a patient;
determining whether the patient is at rest based on one or more physiological parameters; and
measuring a basal/resting heart rate of the patient in response to a determination that the patient is at rest, wherein the plurality of threshold heart rates are defined based on the measured basal/resting heart rate;
defining a plurality of threshold heart rates and rate-dependent sensitivity levels for detecting arrhythmic ECG episodes, wherein the plurality of threshold heart rates are defined based on the measured basal/resting heart rate, wherein more clinically relevant heart rates are assigned rate-dependent sensitivity levels with higher sensitivities;
monitoring ECG signals associated with a patient using a monitoring device; and
processing the monitored ECG signals using the plurality of threshold heart rates and rate-dependent sensitivity levels to detect and capture arrhythmic ECG segments.

Abstract
A system and method for detecting arrhythmic electrocardiogram (ECG) signals includes defining a plurality of threshold heart rates and rate-dependent sensitivity levels for detecting arrhythmic ECG episodes, wherein more clinically relevant heart rates are assigned rate-dependent sensitivity levels with higher sensitivities. ECG signals are monitored by a medical device, and monitored ECG signals are processed using the plurality of threshold heart rates and rate-dependent sensitivity levels to detect and capture arrhythmic ECG segments.
