[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.
This relationship can be perfect positive, strong positive, weak positive, no correlation, weak negative, strong negative, or perfect negative. Scatter plots are a good visual representation of data sets that can hint at what type of correlation is present.
