Abstract
A method for identifying a susceptibility of a subject to atrial-rhythm disturbances includes a) placing a plurality of sensors on the subject to measure a physiologic signal of the subject, and b) recording the physiologic signal from the sensor. The physiologic signal includes an atrial electrical activity of the subject. The method includes c) determining a beat-to-beat variability in the atrial electrical activity of the subject. The beat-to-beat variability includes alternans of electrocardiographic waveforms of a predetermined number of a sequence of heart beats. The method includes d) determining a susceptibility to atrial-rhythm disturbances of the subject using the beat-to-beat variability in the atrial electrical activity determined in step c), and e) generating a report of the susceptibility to atrial-rhythm disturbances of the subject.

8. A method for identifying a susceptibility of a subject to atrial-rhythm disturbances, comprising the steps of:
-
a) placing a sensor on the subject to measure a physiologic signal of the subject; b) recording the physiologic signal from the sensor, the physiologic signal including an electrical activity of a heart of the subject; c) determining a beat-to-beat variability in the atrial electrical activity of the subject during a sequence of heart beats; d) determining a susceptibility to atrial-rhythm disturbances of the subject using the beat-to-beat variability in the atrial electrical activity; and e) generating a report of the susceptibility to atrial-rhythm disturbances of the subject. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system for identifying susceptibility to atrial-rhythm disturbances, comprising:
-
a plurality of sensors configured to measure a physiologic signal of a subject; a computer for recording the physiologic signal from the sensor, the physiologic signal including an atrial electrical activity of the subject, the computer being configured to; determine a beat-to-beat variability in the atrial electrical activity of the subject, the beat-to-beat variability including alternans of electrocardiographic waveforms of a predetermined number of a sequence of heart beats, and use the beat-to-beat variability in the atrial electrical activity to determine a susceptibility to atrial-rhythm disturbances of the subject; and a user interface for displaying the susceptibility to atrial-rhythm disturbances of the subject. - View Dependent Claims (16, 17, 18, 19, 20)
