Abstract
A medical device performs a method for determining a cardiac event by obtaining a signal comprising cardiac cycle length information in a patient and determining cardiac cycle lengths during an established time interval. Noise is detected during the time interval and a cardiac cycle length corresponding to a time of the detected noise is rejected. Cycle length differences are determined from the cycle lengths not rejected during the time interval. The cardiac event is determined in response to the cycle length differences.
