An arrhythmia alarm processor has a pattern extractor and a predetermined reference pattern. The pattern extractor has an output responsive to short duration, intermittent oxygen desaturations of a patient as determined by a fast blood oxygen saturation processor incorporated within a pulse oximeter. The reference pattern is indicative of a series of oxygen desaturations resulting from an irregular heartbeat. An alarm is triggered when the pattern extractor output matches the predetermined reference pattern.
