Methodology of head-up tilt testing in patients with unexplained syncope

open access: yesJournal of the American College of Cardiology, 1991
Prolonged 60 degree head-up tilt has been shown to be valuable in the investigation of unexplained syncope, diagnosing neurally mediated bradycardia/hypotension or malignant vasovagal syndrome. To evaluate the methodology of tilt testing, the following were examined: reproducibility of results, tilt duration, angle of tilt, method of tilt support and ...

Characteristics of head‐up tilt testing with additional adenosine compared with head‐up tilt testing with isoproterenol and isosorbide dinitrate [PDF]

open access: yesJournal of Arrhythmia, 2014
AbstractBackgroundHead‐up tilt (HUT) testing is used to establish the diagnosis of neurally mediated syncope (NMS). Adenosine administration during HUT testing is useful for inducing NMS. However, no comparison between adenosine HUT testing and HUT testing using other drugs has been reported.
