<p>The presence of an irregular heartbeat pattern and/or possible atrial fibrillation is determined by analyzing a measured pulse rate pattern or heart rate pattern. The standard deviation and mean of time intervals each corresponding to a respective heartbeat are determined and compared to a threshold value. When quotient formed by dividing the standard deviation by the mean has a value greater than or equal to the threshold value, the rhythm is irregular. When quotient formed by dividing the standard deviation by the mean has a value less than the threshold value the rhythm is regular.</p> |
