[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.
The scatter plot here reveals. 1  a basic linear relationship between X and Y for most of the data, and. 2  a single outlier (at X = 375).
