Claim One:
1. A computer-implemented method for analysis of an electrocardiogram, the method comprising segmenting the electrocardiogram into different segments corresponding to different cardiac features using a Hidden Markov Model, the model comprising a plurality of states corresponding to the different cardiac features; wherein: the segmenting is performed using two or more Hidden Markov Models corresponding only to a subset of the cardiac features the subset comprising the QRS co ex and the T wave within the QT interval of an electrocardiogram, the QT interval being the period from Q onset to T offset in the electrocardiogram, the segmenting to identify the T wave bein erformed based on the estimated position of T offset as the end point of the QT interval, and wherein the position of the endpoint of the QT interval is obtained from a relationship between heart rate and QT interval.
