[Article in German] BÃ¶hm M. Adenosine has a negative inotropic effect in cardiac atrial preparations (direct negative inotropic effect). This effect is probably due to an activation of a potassium outward current which shortens the action potential duration and hence reduces the force of contraction.
A scatterplot is a graph that is used to plot the data points for two variables. Each scatterplot has a horizontal axis (x-axis) and a vertical axis (y-axis). One variable is plotted on each axis.
A straight line that best represents all data points of a scatter plot. This line may pass through some, all, or none of the points displayed by the scatter plot. Also referred to as a Trend Line or Regression Line.
