title: [Determination of the cause of repetitive syncopal States with the help of registration of electrocardiogram at the background of provocative test].
abstract: A clinical case of repetitive syncopal states in an adolescent with episodes of significant asystoles lasting up to 32 s is presented. These episodes were detected only with the help of electrocardiogram registered during provocative test. Beyond provoking factors the child had signs of insignificant sinus node dysfunction which did not allow to designate the state of the patient as severe and prescribe adequate treatment. We consider this case as demonstration of necessity of provocative tests in conjunction with ECG monitoring in children with episodes of fainting (syncopal states).
