The device of claim 13, wherein said first sensor comprises an accelerometer. 15. The device of claim 13, wherein said first sensor comprises a gyroscope. 16. The device of claim 13, wherein said second sensor comprises a photosensor. 17. The device of claim 13, wherein said discordance is determined to be present when said activity level value is normal and said heart rate value is elevated. 18. The device of claim 13, wherein said computer program includes instructions that cause said processor to determine a heart rate variability value. 19. The device of claim 18, wherein said discordance is determined to be present when said activity level value is normal, said heart rate value is elevated, and said heart rate variability value is increased. 20. The device of claim 18, wherein said computer program includes instructions that cause said processor to indicate a presence of atrial fibrillation. 21. The device of claim 18, wherein said discordance is determined to be present when said activity level value is normal, said heart rate value is elevated, and said heart rate variability value is decreased. 22. The device of claim 21, wherein said computer program includes instructions that cause said processor to indicate a presence of a supraventricular tachycardia. 23. The device of claim 13, wherein said computer program includes instructions that cause said processor to set one or more threshold values based on said activity level value and said heart rate value. 24. The device of claim 23, wherein said one or more threshold values is determined using a machine learning algorithm.
