Key result
Playing computer games reduced nonlinear heart rate parameters such as the SD1/SD2 ratio, correlation dimension, and Lyapunov exponent, while increasing entropy.
Why the study?
To investigate the impact of computer games on sympathetic and parasympathetic nerves and measure the variation of the heart rate signal during playing computer games.
Does playing computer games alter heart rate signal parameters in human subjects?
Observational
Does playing computer games alter heart rate signal parameters in human subjects?
Playing exciting and fear-inducing computer games alters heart rate variability, reducing nonlinear parameters like SD1/SD2 and increasing entropy.

Computer gaming acutely alters nonlinear HRV dynamics in humans; hypothesis-generating and should not yet inform clinical practice or risk assessment.
In this study, we investigate the impact of computer games on sympathetic and parasympathetic nerves and measure the variation of the heart rate signal during playing computer games. To do this, the human subject's heart rate was measured when performing two different computer games (exciting and fear games). The heart rate signal was recorded using heart rate sensors. The heart rate signal was processed using linear and nonlinear methods. SVM classifiers was used to classify different states. The results show that during playing games, the values of nonlinear parameters such as the ratio of SD1 / SD2, correlation dimension, and the Lyapunov exponent were reduced and the entropy was increased.

Haghshenas et al. (2019) reported an observational. Playing computer games (exciting and fear games) was evaluated on Variation of the heart rate signal (linear and nonlinear parameters). Playing computer games reduced nonlinear heart rate parameters such as the SD1/SD2 ratio, correlation dimension, and Lyapunov exponent, while increasing entropy.
