1. A method for measuring variability between direct heartbeat data and indirect heartbeat data, the method comprising:
- receiving first heartbeat data from an electrocardiogram over a period of time;
receiving second heartbeat data from an indirect measure of heartbeat data over at least a portion of the period of time;
calculating, by a computing device, a difference between the first heartbeat data and the second heartbeat data; and
comparing the difference to determine a variation.

Abstract
One method for measuring variability between direct heartbeat data and indirect heartbeat data includes: receiving first heartbeat data from an electrocardiogram over a period of time; receiving second heartbeat data from an indirect measure of heartbeat data over at least a portion of the period of time; calculating, by a computing device, a difference between the first heartbeat data and the second heartbeat data; and comparing the difference to determine a variation.

9. A method of displaying heart rate variability, the method comprising:
-
receiving first heartbeat data from an electrocardiogram over a period of time; receiving second heartbeat data from an indirect measure of heartbeat data over at least a portion of the period of time; selecting a better signal from between the first heartbeat data and the second heartbeat data; calculating, by a computing device, a measure of the variance in heartbeat intervals in the better signal; and displaying the heart rate variability data. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of displaying heart rate variability, the method comprising:
-
receiving heartbeat data from a pulse oximeter oxygen saturation sensor; compensating for external variations in beat-to-beat intervals of the heartbeat data; performing a spectral analysis of the heartbeat data; and displaying the spectral analysis. - View Dependent Claims (16, 17)
