Objective: This study aimed to evaluate the correlation between fragmented QRS complex (fQRS), aortic stiffness, and diastolic dysfunction in hemodialysis patients. Subjects and Methods: A sample of 56 patients who received hemodialysis treatment was stratified into 2 groups according to their electrocardiography (ECG) patterns with or without fQRS. Baseline characteristics and laboratory parameters of patients were documented. Conventional echocardiographic and Doppler echocardiographic procedures were performed in all patients. The mean early (Em) diastolic and late (Am) diastolic myocardial velocities were calculated. These tests were performed before dialysis. The Student t test, Mann-Whitney U test,. 2 test, Spearman correlation, and multivariate linear regression analysis were used to analyze parameters where appropriate. Results: Of the 56 patients under hemodialysis, fQRS in ECG was detected in 26 (46.4%). Echo-cardiographic evaluation showed that deceleration time (237.57 +/- 40.10 ms; p = 0.030), isovolumic relaxation time (126.84 +/- 15.62 ms; p < 0.001), early (E)/late (A) ventricular filling velocity (E/A) ratio (1.15 +/- 0.40; p |
