Evaluation complaints of palpitations in patients with Fibromyalgia Syndrome

Objective: To research the effect of Fibromyalgia Syndrome (FMS) on the cardiac conduction system and evaluate the feasibility of ECG parameters in estimating arrhythmia development with 24-hour ambulatory Holter ECG monitoring. Method ECG was taken for all participants of the study. ECG parameters were measured. 24-hour ambulatory Holter ECG monitoring was made and analyzed. Result 90 patients with FMS and 70 controls were enrolled in the study. The average age of the patient group was 38.3 ± 6.3 years, and the female patient population (73.3%) was almost three times the number of male patients (p = 0.032). In terms of clinical features such as age (p = 0.301), height (p = 0.789), weight (p = 0.628), and body mass index (BMI) (p = 0.770), there was no significant difference between the study and control groups. There was no significant difference between the groups in terms of heart rate (p = 0.800), systolic blood pressure (p = 0.394), and dyslipidemia (p = 0.133). In terms of routine blood tests, there was no significant difference between the study and control groups (p > 0.05). In the comparison of ECG parameters, Pmax, QTd, and QTcd were statistically significant in the study group compared to the control group (p  0.05). There was no significant relationship between the study group and the control group in terms of 24-hour Holter ECG recording results (p = 0.182). Conclusion Although FM patients complain of palpitations, the outcomes of the study showed that the risk of arrhythmias was not increased.
