Tilt testing results are influenced by tilt protocol [PDF]
Europace, 2015 It is unknown how the return to supine position influences duration of loss of consciousness (LOC) and cardioinhibition during tilt test.Retrospective analysis of two datasets containing records of patients who underwent tilt testing for unexplained syncope in two centres was performed.

Tilt testing remains a valuable asset [PDF]
European Heart Journal, 2021 AbstractHead-up tilt test (TT) has been used for >50 years to study heart rate/blood pressure adaptation to positional changes, to model responses to haemorrhage, to assess orthostatic hypotension, and to evaluate haemodynamic and neuroendocrine responses in congestive heart failure, autonomic dysfunction, and hypertension. During these studies,

Progressively invalidating orthostatic hypotension: A common symptom for a challenging diagnosis
Journal of Research in Medical Sciences, 2016 We discuss here an uncommon condition of neurogenic hypotension in the context of immunoglobulin light chain (amyloid light-chain) amyloidosis. The most serious feature was autonomic nervous system impairment, mainly characterized by severe refractory ...

Underlying hemodynamic differences are associated with responses to tilt testing
Scientific Reports, 2021 Aim of this study was to explore whether differences in resting hemodynamic parameters may be associated with tilt test results in unexplained syncope. We analyzed age, gender, systolic (SBP), diastolic blood pressure (DBP) and heart rate (HR) by merging
