<p>A system for use in analysis of electrograms comprising: an input signal generator (302); an input electrode (304) for applying an input signal to a driving region of a heart (316); an output electrode (306a-c) for receiving an output signal at a driven region of the heart; a processing system (300) operable to receive signals indicative of said recorded value from the output electrode for analysing conduction paths through the heart, wherein the signal generator is operable to generate an input signal comprising a plurality of pulses, being spaced from each other by a pacing interval; and the processing system being arranged to identify signal delay between the input signal and the output signal on the basis of the signal received by the output electrode in relation to the plurality of pulses, and to identify a rate of variation in signal delay over a range of values of pacing interval.</p> |
