1. An apparatus for monitoring activation in a heart, the apparatus comprising a probe, a plurality of electrodes supported on the probe and extending over a detection area of the probe, the detection area being arranged to contact a detection region of the heart, wherein each of the electrodes is arranged to detect electrical potential at a respective position in the heart during movement of a series of activation wavefronts across the detection region, a display screen, and a processor configured to:
process and analyse the detected electrical potentials to identify a plurality of wavefronts passing the detection region;
for each of the plurality of wavefronts, identify a transition period during which the wavefront crosses the detection region and define a series of update intervals occurring during the transition period;
for each of the update intervals to determine a propagation direction; and to control the display screen to generate a display indicative of the direction.
