Abstract :Objective: The occurrence of symptoms in patients with mitral valve prolapse insert ignore into journalissuearticles values(MVP); is linked to autonomic dysfunction and neuroendocrine causes rather than progressive mitral valve insufficiency. The goal was to assess the risk of autonomic dysfunction and arrhythmia in patients with MVP. Methods: The study included 63 patients with primary MVP and a control group of 64 children of similar age and gender. Following a physical examination, all patients\` histories were taken, and 12-lead ECGs, autonomic function tests, echocardiography, and 24-hour Holter rhythm studies were performed. Results: The patient group had a higher mean resting heart rate than the control group. Orthostatic hypotension was found in 8 patients insert ignore into journalissuearticles values(12.6%); and 4 children insert ignore into journalissuearticles values(6.2%); in the control group. When compared to the control group, patients with MVP had higher QTc dispersion, frontal QRS-T angle, Tp-e interval, and Tp-e/QTc ratio. There was no significant difference between the two groups in terms of conventional measurements of heart rate variability in the Holter ECG, as well as no significant difference in HRDC. Conclusion: Although cases with pathological findings in the initial ECG were excluded from our study, we believe that the high frontal QRS-T angle observed in MVP patients is a novel and significant finding. Furthermore, it has been discovered that HRDC, a new and understudied parameter in children, does not show a significant difference in patients with MVP.
