1. A method for detecting an A-wave, the method comprising:

  • applying a series of stimuli to a nerve;

    recording a series of evoked bioelectrical responses;

    identifying one or more attributes in each of the responses;

    utilizing each of the one or more attributes of each of the responses to create a new data set;

    creating a search window that is smaller than the new data set;

    searching the new data set for trends by;

    sequentially applying the search window across the new data set; and

    analyzing the search window by counting the number of data points contained within the search window at each separate, sequential search window position;

    analyzing the new data set by;

    registering a positive for an A-wave component if the number of data points contained within the search window at each separate, sequential search window position exceeds a predetermined threshold; and

    registering a negative for an A-wave component if the number of data points contained within the search window at each separate, sequential search window position does not exceed a predetermined threshold; and

    consolidating the A-wave components into a single A-wave.
