An Adaptive and Time-Efficient ECG R-Peak Detection Algorithm

Pseudocode 1: The pseudocode of the threshold procedure.

Tref = localmax1; Cref = localmax2; Rref=localmax3; t_p = time period (abs (Tref - Cref));

WTref = width (Tref); WCref = width (Cref); ATref = amplitude (Tref); ACref = amplitude (Cref);

If t_p < ti_t

  If WTref < WCref

    localmax1 is a true R-peak;

    Else if WTref > WCref

      localmax2 is a true R-peak;

      Else if ATref > ACref

        localmax1 is a true R-peak;

        Else

          localmax2 is a true R-peak;

      End if

    End if

  Else

    localmax1 is a true R-peak;

  End if

End if

If Rref is not NULL

  False R-peak is replaced by the Rref, and repeat the algorithm with new Tref and Cref;

End if
