Objective: The aim of our study is to evaluate the chronotropic incompetence and cardiac functions in patients who have had Covid-19 infection and recovered, to understand what kind of effects Covid-19 infection has on the heart and to what extent the chronotropic response of the heart to the exercise test, and to determine the long-term cardiovascular system effects of Covid-19 infection. Method: Thirty patients who applied to the cardiology outpatient clinic between February 1, 2021 and May 1, 2021, whose Covid-19 infection was confirmed by laboratory sampling and whose complaints continued after recovery, and who met the study criteria, were included. Sixty people matched for age and sex were included as the control group. In the routine evaluation of the cardiology outpatients clinics, height, weight and waist circumference were measured as in each patient, and 12-lead electrocardiography was performed for each patient, followed by echocardiography and exercise stress tests. Chronotropic incompetence, chronotropic index (CI), heart rate reserve (HRR), and echocardiographic data were calculated. Chronotropic index ≥8 was considered normal. The variables were compared between the 2 groups. Results: In patients with persistant symptoms after Covid-19, chronotropic incompetence and abnormal chronotropic index rates were found to be significantly higher (p=0.002; p
