1. A system, comprising:

  • a controller connected to a sense and pulse delivery module, the controller adapted to receive signals from one or more electrodes and provide pulse instructions for delivery of pulses to the one or more electrodes; and

    an event window generator connected to the controller, the event window generator adapted to produce event windows for cardiac contraction events, the event windows each being a function of a plurality of intervals between atrial contraction events and a heart rate trajectory being a time derivative of heart rate,wherein the controller is adapted to produce an instruction for delivering a pulse if a cardiac contraction event is not detected during an event window beginning from a former cardiac contraction event.
