Assessment of atrial electromechanical delay in children with acute rheumatic fever.

[acute rheumatic fever]

There may be an increase in the risk of atrial arrhythmia due to left atrial enlargement and the influence on conduction system in acute rheumatic fever . The aim of this study is to investigate atrial electromechanical delay and P-wave dispersion in patients with acute rheumatic fever .A total of 48 patients diagnosed with acute rheumatic fever and 40 volunteers of similar age , sex , and body mass index were included in the study . The study groups were compared for M-mode echocardiographic parameters , interatrial electromechanical delay , intra-atrial electromechanical delay , and P-wave dispersion .Maximum P-wave duration , P-wave dispersion , and interatrial electromechanical delay were significantly higher in patients with acute rheumatic fever compared with the control group (p < 0 .001 ). However , there was no difference in terms of intra-atrial electromechanical delay (p > 0 .05 ). For patients with acute rheumatic fever , a positive correlation was identified between the left atrium diameter and the P-wave dispersion and interatrial electromechanical delay (r = 0 .524 and p < 0 .001 , and r = 0 .351 and p = 0 .014 , respectively ). Furthermore , an important correlation was also identified between the P-wave dispersion and the interatrial electromechanical delay (r = 0 .494 and p < 0 .001 ).This study shows the prolongation of P-wave dispersion and interatrial electromechanical delay in acute rheumatic fever . Left atrial enlargement can be one of the underlying reasons for the increase in P-wave dispersion and interatrial electromechanical delay .
