Slope Calculation

The calculation of the slope of each data point (P) is achieved by linear regression. This linear
regression is performed within a time interval around each data point. Increasing the interval
will help to reduce noise on the slope.

The time interval around a data point P can be defined by the user in the "Analyze" dialog
of the "QT-related Analysis" tab in Cardio2D+. Please read also chapter "QT-related Analysis".

Select time span for the "Slope Calculation" in ms in the up down box to define the size of the
time interval which is used for slope calculation of each point of the signal. Please see the picture.
