Provided are controllers, methods and systems for monitoring cardiac data for the presence of arrhythmia. A controller as provided comprises input means arranged to receive first cardiac data corresponding to a time period, processing means and output means. The processing means is arranged to identify, within the first cardiac data, a plurality of events corresponding to ventricular contraction, and a time associated with each event; determine a plurality of intervals between the times associated with chronologically successive events; and produce second cardiac data in dependence on the determined intervals. The output means is arranged to transmit an output signal to a display means based on the second cardiac data, for displaying a beat-to-beat display plot corresponding to at least a part of the time period on the display means. A system as provided may comprise such a controller and a display means for displaying the beat-to-beat display plot corresponding to at least a part of the time period. Also provided are methods of analysing and monitoring cardiac data for the presence of arrhythmia, and non-transitory, computer-readable storage media which store instructions thereon that when executed by one or more processors causes the one or more processors to carry out such a method.
