Claim One:
1. A non-transitory computer readable medium containing computer executable instructions that can be executed by a processor to predict the onset of atrial fibrillation (AF) from electrocardiogram (ECG) data representing a patient, the executable instructions comprising: a signal processing component that determines parameters representing the activity of the heart of the patient from the ECG data, the signal processing component comprising a premature atrial contraction (PAC) detection system that identifies premature atrial contractions represented by the ECG data; a feature extraction component that calculates a plurality of features from the determined parameters, at least one feature being calculated from the detected premature atrial contractions; and a classification component that determines an AF index for the patient, representing the likelihood that the patient will experience AF, from the calculated plurality of features; wherein the AF index is output to a cardiac monitoring apparatus.
