13. An Atrial Fibrillation (AF) analysis method comprising:
-
obtaining an output that includes a heart beat; deriving a heart beat interval; analyzing a number (N) of heart beat intervals from the output; and detecting a likelihood of AF by; calculating a Turning Points Ratio (TPR) of the N heart beat intervals; calculating a root mean square of successive (RMSSD) heart beat intervals; and calculating Shannon Entropy (SE) of the N heart beat intervals. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. An apparatus for Atrial Fibrillation (AF) detection, the apparatus comprising:
-
a sensor for obtaining an output that includes a heart beat; and a processor for deriving a heart beat interval from the output, and analyzing a number (N) of heart beat intervals from the output, wherein a likelihood of AF is detected by; calculating a Turning Points Ratio (TPR) of the N heart beat intervals, calculating a root mean square of successive (RMSSD) heart beat intervals, and calculating Shannon Entropy (SE) of the N heart beat intervals.
