In the contemporary society, people are subject to to various mental loads resulting in stress, the so-called stress became a part of our lives that we cannot avoid. Therefore, the need for a device that can easily measure the stress in every day life is rising. In this research, Poincare plot and mental stress were visually evaluated using the cardiac beat-to-beat interval known as RR interval. It has been understood that the heart rate variability was concentrated in the lower left-hand side of the Poincare chart in the case of mental stress while it was overall scattered in the case of relaxation. Moreover, it was confirmed that a clearer difference could be shown by plotting the Poincard plot for RR intervals corresponding to the breathing cycles.
