Study progress of ambulatory blood pressure monitoring in the diagnosis of children with syncope / 中华实用儿科临床杂志

ABSTRACT

Eighty percent of unexplained syncope in children is neurally mediated syncope (NMS).The cur-rent clinical diagnosis of children NMS mainly depends on the head -up tilt test(HUTT),which has a certain risk, therefore searching for a safe noninvasive NMS diagnosis method is of great significance.Twenty -four -hour ambulato-ry blood pressure monitoring (ABPM)is widely used in clinic recently.It was reported that there was autonomic nerve adjustment imbalance in children with NMS.And the diagnostic value of ambulatory blood pressure pattern to NMS chil-dren was high.Non -spoontype blood pressure variation pattern of NMS could aid to diagnose children NMS.Fur-therly study of 24 h ABPMof NMS children has great significance to explore the pathogenesis of the NMS,to be benefi-cial to explain the regulating mechanism of the vessels,and go a step further to guide the treatment.
