Can the result of a tilt test be predicted in the first five minutes?
Patients with VVS have disturbed sympathovagal balance at rest. Our data suggests that the results of HUT could be predicted by analyzing the spectral parameters of HRV during the first five minutes of the test. The reaction to orthostasis in patients with syncope during the Westminster protocol was more severe compared to the Italian protocol group and the control group. Vasovagal response during the Italian protocol may be triggered by drug-induced vasodilatation.
The high degree of application does not correspond with the results of previous studies on guideline compliance with external guidelines. A possible explanation of this may be the change made of the external guideline to a guideline within the hospital.
