A medical device performs a method for detecting atrial arrhythmias. A signal including ventricular cycle length information is sensed in a patient and used to determine each difference between successive ventricular cycle lengths occurring during a predetermined time period. Each succeeding difference is stored as a data point in a histogram, and a metric of variability of the data points of the histogram is determined. An atrial arrhythmia is detected in response to the metric crossing a threshold. The threshold is determined in response to the number of ventricular cycle lengths occurring during the predetermined time period.
