Patent attributes
A method and apparatus to determine possible atrial fibrillation that includes detecting irregular pulse rhythms from a succession of time intervals each corresponding to a respective interval of time between successive pulse beats of a sequence of the pulse beats; analyzing the detected irregular pulse rhythms to make a determination of possible atrial fibrillation; indicating the possible atrial fibrillation from the determination. If a sphygmomanometer is used, a plurality of pulse beats may be detected with it including the sequence of pulse beats; and respiratory variation in systolic pressure of the pulse beats may be compensated by designating the succession of time intervals to exclude at least an initial one of the plurality of time intervals.
