Abstract
A method and apparatus for detecting atrial arrhythmias include acquiring a cardiac signal comprising R-waves. Differences between pairs of consecutive R-R intervals occurring during a first time interval are computed from the cardiac signal. An atrial arrhythmia is detected subsequent to the first time interval in response to the computed differences. Storage of the cardiac signal is triggered in response to the atrial arrhythmia detection.
