摘要：
A method and apparatus for detecting a cardiac event in a medical device determine an activity level count from an activity sensor signal for each of a number of time segments, store an activity level count for each of the time segments in a histogram, and accumulate the stored activity level counts to determine a percentage of time segments having an activity level count above a given activity level count.
