Background: Our aim was to evaluate electrocardiographic and echocardiographic properties and exercise response of patients with fibromyalgia (FM).

Methods: The study included 60 women with primary FM and 30 healthy individuals. Resting electrocardiography, echocardiography and exercise treadmill test were used to compare these two groups. At apical four-chamber window, samples of transmitral diastolic inflow and tissue Doppler imaging of left ventricle lateral wall were obtained. Left ventricle ejection fraction was measured via modified Simpsons method. Exercise duration, maximal exercise capacity, maximal heart rate (HR) (bpm), maximal HR (%), rate-pressure product at maximal HR (bpm mmHg), heart rate recovery 1 (bpm), heart rate recovery 2 (bpm) and chronotropic reserve (%) values were calculated.

Results: Resting HR and QTc values were similar in both groups. Echocardiographic measurements in both groups did not reveal statistically significant difference except left ventricle end-diastolic diameter and left atrial diameter. Parameters related to diastolic function of the left ventricle did not differ significantly in both groups. Also, there was not any significant difference between the groups for E/E ratio and chronotropic reserve. Exercise treadmill test results were statistically similar for both groups.

Conclusion: Patients with FM presented a normal HR response to exercise and those patients had normal diastolic function similar to their healthy controls.
