Burdick E350i calculation of PR interval

I need to find out if the E350i interpretation algorithm calculation of PR interval uses a mean or a median.  The Operators Manual does not say.  A seasoned Burdick tech told me this information would be in the "Physician Guide" that came with the machine when new.  I have not been able to locate one. Please let me know if you can tell me mean or median or have access to a "Physician Guide".  Thank you

 As stated in the “physician’s guide”:

 PR Interval

 Omit this section if:

  1.   The P wave flage (from rhythm analysis) is not set.
  2.   The rhythm is not NOT SINUS RHYTHM
  3.  WPW syndrome is present

 

    STATEMENT      

  1. Short PR: Possible Ventricular

     Preexcitation

  1.     The PR interval is less than the lower limit for age as specified in the table.

             Age range                :             lower limit

              In years                   :             in seconds

 

                  0-2                       :               0.07

                  3-11                     :               0.9

                  12 +                      :               0.10

 

  1.  SHORT PR INTERVAL
    1.    0.10s  < PR interval <0.11s

             And     (b)       age >_  12

  1.     FIRST DEGREE A-V BLOCK
    1.   PR interval >_ 0.22s
  2.    BORDERLINE FIRST DEGREE A-V BLOCK
    1.    0.20s <_ PR INTERVAL <0.22s

 

       NOTE: The statements 3 and 4 are determined by the rhythm analysis.
