Abstract:
Objective To explore the relationship between unexplained sighs in children and head-up tilt test (HUTT).Methods Ninety-six cases of children with the main symptom of unexplained sighs were received at Specialist Out-Patient Clinic of Children's Syncope from May 2003 to Mar.2012 in the Second Xiangya Hospital of Central South University,aged 4-14 years old(50 cases were male,46 cases were female),with a mean age of (8.55 ±2.71)years.The detailed history,physical examinations,conventional 12 lead electrocardiogram,chest x-ray,and echocardiography were all investigated,as well as the examination of myocardial enzyme,to eliminate the disorders of organic chest wall,heart,lung disease,and then HUTT inspection was given to them.Results HUTT positive rate was 31.25％ (30/96 cases),and no gender differences were found [20.00％ (10/50 cases) vs 43.48 ％ (20/46 cases),x2 =3.196,P ＞0.05].The positive cases included the basic head-up tilt table test in 2 cases(6.67％) and sublingual nitroglycerin head-up tilt test in 28 patients(93.33％).The hemodynamic changes in HUTT were found in 26 cases of vascular inhibited type(86.67％),heart inhibited type in 1 patient(3.33％) and the mixed type in 3 cases(10.00％).Conclusions Almost a third of children with unexplained sighs are related to the autonomic function disorder.HUTT may help to determine the causes of clinical unexplained sighs in children.
