Dear Editor, We read the article titled “Evaluation of cardiac autonomic nervous system in patients with ankylosing spondylitis using 12-lead electrocardiography and Holter monitoring” by Candemir et al. in the current issue with great interest and curiosity. First of all, we would like to congratulate the authors on this novel study. We saw that both heart rate variability (HRV) and heart rate turbulence (HRT) parameters were impaired in ankylosing spondylitis (AS) . We decided to add some comments about this article that will be helpful.
