Additionally, we evaluated QT parameters (QT maximum, QT minimum and QT dispertion) with the use of electrocardiography in order to measure the autonomic dysfunction which is a possible mechanism in the pathogenesis of the disease. Methods: The study was performed on 42 patients (mean age 41 years, 38 female) and 38 completely healthy subjects (35 female, mean age of 42 years) who were admitted to the same clinic were collected as the control group. All the individuals were undergone a complete physical examination, electrocardiography (recordings were displayed at 50 mm/s speed) and echocardiography evaluation (both conventional methods and TDE). Results: Analysis of electrocardiographic recordings revealed mildly increased mean QT dispertion in the patient group, but this difference was statistically insignificant. Analysis of conventional echocardiographic parameters revealed similar results between the patient group and the control cases. However, an important finding of this study is that significant diastolic dysfunction was found in the patient group which was recorded with the TDE technique. Em wave velocity and Em/Am ratios were significantly lower in patients with FM compared with controls (p<0.005, p<0.01, respectively). Sm and Am waves velocities were similar in both groups. Conclusion: In this study, significant left ventricular diastolic dysfunction which was detected by TDE technique can partly explain several symptoms such as fatigue and dyspnea in FM. In addition, fully cardiac evaluation of patients with FM might be obtained supporting findings the autonomic dysfunction theory in fibromyalgia pathogenesis. © 2010 Düzce Medical Journal.trinfo:eu-repo/semantics/closedAccessEchocardiography; Fibromyalgia; QT dispertionArticle1211217Q4
