Apparatus for detecting atrial fibrillation in the presence of frequent premature beats

摘要

An apparatus for determining possible atrial fibrillation, comprising means for establishing an average of unasucesión intervals corresponding to a sequence of pulse beats of time; means for determinarvalores bottom and top as a percentage of the respective average limit; wherein the apparatus further comprises means configured to recalculate an average and paracalcular one that delimits the value standard deviation of the succession of time intervals that are at or between the values ​​of lowerbound and above only not correspond to those time intervals that are less lower or higher than the upper limit, and means for determining possible atrial fibrillation based upon a quotient formed by dividing said StdDev by said recomputed average and comparing the ratio with a threshold value.
