Abstract:
1. A system for use in analysis of electrograms, the system comprising: a signal generator for generating an input signal; an input electrode for applying an input signal to a driving region of a heart organ; an output electrode for receiving an output signal at a driven region of the heart organ, so as to record a value thereof; a processing system operable to receive signals indicative of said recorded value from the output electrode for analysing conduction paths through the heart organ, wherein the signal generator is operable to generate an input signal comprising a plurality of pulses, at least some of the pulses from said plurality being spaced from each other by a pacing interval; and wherein the processing system is 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, wherein the processing system is arranged to identify a rate of variation in signal delay over a range of values of pacing interval.
