1. A system, comprising:

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

    an event window generator, connected to the controller, producing event windows for ventricular contraction events;

    one or more sensors connected to the controller; and

    a morphology detection system, connected to the controller, for detecting abnormal complexes,wherein the event windows are a function of ventricular rate and ventricular rate trajectory over a plurality of intervals between ventricular contraction events, signals from the one or more sensors, and information from the morphology detection system.
