There is described a method of characterisation of cardiac electrophysiological behaviour for identifying patients at risk of sudden death from arhythmias, for example associated with hypertrophic cardiomyopathy (HCM). Paced ventricular electrograms are analysed, and latency values of transitions of the electrograms are used to construct conduction curves. Parameters of the curves such as the point of onset of a predetermined increase in latency and the increase in electrogram width in a predetermined interval during the pacing sequence are used to identify and/or characterise physiologically significant features of myocardial disarray.
