ABSTRACT

Objective:

To explore the relationship between unexplained palpitation in children and head-up tilt test (HUTT).

Methods:

A total of 142 children with the main symptom of unexplained palpitation were admitted to the Specialist Out-Patient Clinic of Children's Cardiovascular Disease from Sept.2008 to Feb.2017 in the Second Xiangya Hospital,Central South University.Among them,63 cases were male,79 cases were female,with the mean age of (10.12±2.88) years old.The detailed history,physical examinations,conventional 12 electrocardiogram,chest X-ray,echocardiography,myocardial enzymes and thyroid function were all examined.The disorders of heart disease,systemic disease and drug effect were ruled out.The HUTT inspection was then given to them.

Results:

Among the 142 palpitation cases,79 cases were HUTT positive (55.6%) and 63 cases were HUTT negative (44.4%).The age in HUTT positive patients was older than that in HUTT negative patients (P<0.05),with no significant difference in gender (P>0.05).There were three types of hemodynamic changes in HUTT positive patients.Among them,38 cases were postural orthostatic tachycardia syndrome (48.1%),36 cases were the vasovagal syncope vasodepressive type (45.6%) and 5 cases were the vasovagal syncope mixed type (6.3%).There were no hemodynamic types for vasovagal syncope cardioinhibitory type,orthostatic hypotension and orthostatic hypertension.

Conclusion:

Among the clinically unexplained palpitations children,more than half are caused by unbalanced autonomic nervous function.HUTT can help clear the cause of unexplained palpitations.
